1. Cadence doesn’t matter
After reading Body By Science and starting high intensity strength training for the first time, I made a conscious effort to maintain a specific cadence during all exercises. I started doing 10/10 and then experimented with 5/5 after reading Occam’s Protocol in The 4-Hour Body by Tim Ferriss (seeking quick unachievable gainz … ). I found that monitoring cadence in this way and counting the seconds in my head subtracted from the productivity of the exercise. I was already trying to focus on my breathing, effort, and form and this was just another variable to add to the list.
Back then, I had much less knowledge of resistance training and specifically the role that cadence played with regard to exercise outcomes. I now believe that cadence doesn’t really matter at all with respect to improvements in strength and muscle hypertrophy. I don’t think that moving faster or slower during an exercise is going to improve these outcomes.
Therefore, instead of trying to stick to a set cadence, I now focus on quality of movement and let that determine the cadence. On every exercise I perform, I make sure my turnarounds at either end of the exercise are as smooth as possible. I try to move so smoothly that a spectator would think I’ve stopped moving (as per Drew Baye’s bodyweight squat demo here) I may move quite briskly during the middle of a given exercise but I will not move explosively. I won’t move explosively to avoid cheating with momentum and causing injury. As a result, my cadence will increase over time as I become more fatigued during the exercise. What might start as an organic 6/6 may become a 10/10 towards the end of a set. During the last few repetitions, I will move through the middle of the range of motion as fast as possible. There is no danger at this juncture since I’m so fatigued that my fastest movement is slow, and thus, I won’t move fast enough to cause an injury. Force = Mass X Acceleration.
I still measure time-under-load for every exercise, since I like to track performance between workouts and use this as a guide to know when to increase exercise difficulty/resistance. However, so long as my form is good and my turnarounds are smooth, I don’t concern myself with cadence and let it express itself organically. As per many people who have been doing HIT for a long period of time, I am always trying to improve the quality of my exercises. This pursuit of mastery has a real meditative quality to it.
Lastly, I’ve read comments from people new to HIT who ask for recommendations on cadence. I responded with something similar to the above regarding organic cadence but they still wanted some kind of benchmark. I think a 4/4 is a good starting point. However, one will soon come to realise just how arbitrary this really is.
Here’s some examples of my attempt to master form during a Big-3 Bodyweight High Intensity Training workout:
2. Experiment with frequency and volume
When I first started high intensity training, I was very rigid in my approach. Body By Science is an amazing book and completely changed my understanding of exercise and what it meant to exercise effectively and efficiently. However, like many newbies to HIT, I became dogmatic about certain high intensity training principles that seem to still be up for debate within the scientific community such as volume, frequency and intensity.
During the first couple of years of my training, I followed Body By Science quite closely. I never trained more than once per week and I quickly began increasing my recovery time and abbreviating my workouts. At one point, I was doing a 2-way-split every 7-10 days. My workouts lasted just 6-minutes. Even with such little volume, I got great results. I developed muscle and strength very effectively by training in this way and was able to maintain my gains. Here’s a picture of me on a camping trip during this time:
Freezing my balls off in a river in the Lake District, UK.
In the last few years, having read more around high intensity training and interviewed many experts/people with different experiences, I restored a healthy skepticism for what I had learnt at the beginning of my HIT journey. This inspired me to do more self-experimentation. Hence the foray into body weight high intensity training and Project Kratos, which I’ve journaled some of here (Part 1, Part 2, Part 3 and Part 4).
Since I believe I’ve probably tapped out most of my muscular potential, it’s quite likely that increasing my frequency to twice per week and thus total weekly volume will have no effect on more muscle gain but it doesn’t seem to have a negative effect either. Depending on shifting priorities, I’ll revert to once a week training in the future for more convenience. The point is that I’m trying to keep an open mind, ready to question my strongest beliefs in the face of new evidence and experience.
I encourage you not to get discouraged by conflicting evidence and online debate and consider experimenting with varying intensity, volume and frequency, as Dr Doug McGuff describes here.
3. Don’t be afraid to do more
During my early days in high intensity training, I became obsessed with trying to “optimise” recovery. I was religious about planning rest days after workouts with no activity. I’d try to orchestrate my workout day to perfection to ensure I didn’t “subtract” from my performance on that day, because it was “so important” that everything was perfect. I know you’ve probably been here too ;-).
I remember on one Saturday evening, I was carrying groceries home from the supermarket with my best friend. I had worked out on the previous day and carrying the groceries made me feel anxious. Anxious I was going to lose my “gains”. I thought I was going to dig into my recovery. To make matters worse, I missed the bus on the way home and had to walk an additional half-mile with all this baggage (Oh no!! LOL). I got so irritated by this that my best friend and house mate at the time had lost patience with me and quickly walked on alone (quite rightly so). I recently shared this story on the round table podcast with Skyler, Drew and Ryan here. I felt so embarrassed re-telling it. It’s so ridiculous.
As Dr Doug McGuff described here, HIT is far more intense than most activities, which means that, if inclined, you can get away with additional sports and recreational activity. However, you may want to avoid anything too strenuous (e.g. sports) for 24-hours after HIT. As a case in point, I recently tore my calf muscle during a basketball game when I decelerated quickly from a sprint. I had performed a Big-5 workout on the day before on machines including a Leg Press. I think the novelty (having trained only bodyweight for over a year prior) and resulting fatigue made me more vulnerable to injury. However, it’s possibly multifactorial and likely the cause of zero warm up as per Skyler Tanner’s thoughts:
4. Move a lot
I’ve been doing progressive resistance training fairly consistently for almost 10 years. I’m relatively strong, capable and flexible but despite this I had some mild back pain. Why is this? This is because I was too sedentary or static for a prolonged period of time. I was sitting too much.
Resistance training or high intensity training is not a cure-all. I do not think it is a healthy practice to workout once or twice a week and sit down until the next workout. Skyler said it best on a round table podcast: “infrequent exercise, frequent movement”.
Many of us spend too much time sitting at desks working, myself included. If I spend too much time sitting, I experience mild pain and discomfort.
Therefore, I’ve made it a habit to interrupt long periods of sitting with intermittent movement. I’ll sit down to work on my most important task for ~2-3 hours, but I will get up 3 or 4 times during that block of time to unload the dishwasher, make a cup of tea, do the laundry, walk outside and move the bins behind the house ;-).
5. Bodyweight vs machines vs free weights: it makes little difference
My first experiences in resistance training prior to HIT focused on free weight exercises: bench press, cable chest flies, and of course, bicep curls. I went to the gym 3 or 4 times a week and spent at least an hour per session. I also used to play basketball 3-times per week, swim, etc, etc. After reading The Spartan Health Regime, I learnt more about muscle function and began to embrace more multi-joint, abbreviated routines, such as:
- Monday: chin-ups and bicep curls
- Wednesday: Push-ups and overhead press
- Friday: Squats and deadlifts
- Note: 3 sets of 5 (heavy loads or weighted chins)
Once I read Body By Science, I switched to all multi-joint exercises and performed the Big-5 on MedX machines once a week for 6-12 months. A couple of years ago, and unfortunately, London’s Keiser Training closed forcing me to re-educate myself on bodyweight training. Starting with Chris Highcock’s Hillfit eBook, I learnt how to construct a productive bodyweight program with very little equipment. I took this to the next level with Project Kratos and I haven’t really looked back. Bodyweight high intensity training requires almost no equipment and can be done practically anywhere.
Until I live near a facility with high quality exercise machines or create my own, bodyweight training will serve me well. Based on my experience, research and conversations with guests on the podcast, it seems like the resistance training mode doesn’t really matter in terms of driving optimal muscle hypertrophy, strength and all of the other health benefits derived from strength training. However, I think that machines are ideal for training some muscles that are otherwise difficult to train effectively like the lower back and neck. Machines are also great for HIT newbies who struggle with the difficulty and complexity of bodyweight and free weight exercises. Machines allow for easier form and greater focus on effort.
I think a perfect workout protocol would probably combine some specialist machines for the neck and lower back with either a free weight, machine, or bodyweight training protocol.
This is how I look after training using high intensity body weight once or twice a week for a couple of years.
6. Track your workouts but don’t get obsessed
When I was a resistance training novice, I didn’t really understand cause and effect and whilst I loosely tracked performance, I was more focused on volume, frequency and bulk dieting aka “more is better”. I was focused on the quantity over the quality. As my training routine evolved, my exercise quantity reduced and quality increased. Volume and frequency came down and quality of exercise form and intensity of effort went up.
As my workouts became more infrequent and more abbreviated, I was very eager to optimise. I was only working out once a week. The workout HAD to be better than last time. I HAD to improve every workout. Otherwise, all of that environmental optimisation stuff: sleep, diet, stress management, etc, was for not …
I became obsessed with tracking. During my first 1-2 years of high intensity training, I tracked total workout time, time-under-load (for every exercise), machine settings and load. If I didn’t improve at least one variable (TUL or load) from workout-to-workout I would become quite unhappy and demotivated. I had assumed that my progress would continue to improve in a linear fashion week-to-week beyond my 6-month introduction to HIT.
I had a major epiphany during my first meeting with Simon Shawcross (Founder of HITuni.com). As we sat across from each other in a cosy London Starbucks, Simon asked me a question: “how do you know if you are keeping all variables the same from workout-to-workout? How do you know if you’re moving with the exact same cadence and form, breathing in the same way, recruiting muscle in the same way, sleeping the same, etc, etc.” he went on “at your stage of training, it makes a lot more sense to look at your training progress over a longer time period, consider reviewing progress every 6-12 weeks and making adjustments if necessary to volume or frequency.” Tim Ryan also believed there are at least 12 factors that affect workout performance. Falling short DOES NOT necessarily mean you’re not recovered.
This was a big turning point for me. It helped me appreciate the importance of training with a high degree of effort during every workout to aim for momentary muscular failure. I became comfortable with understanding that my performance may not improve from workout-to-workout but the stimulus would be sufficient to produce the best results over the long term.
At this juncture of my training career, I still want to improve my physique and try my hardest to improve my performance during every workout. I’m just not obsessed with my results from workout-to-workout. I’m more concerned with my long term performance and just getting it done at least once a week. So long as I’ve been true to myself and trained to failure or as close to failure on every single exercise, I’m happy with that workout performance, regardless of the numbers. In fact, Dr Doug McGuff reminded me that sometimes a shorter TUL on the same load can actually suggest that one is becoming more proficient at fatiguing target musculature more effectively. So, go figure.
My trusty pink performance pad. The meat heads love it.
7. If you miss a session, it’s not the end of the world
Exercise quality and the application of high effort seem to be the most important variables in exercise. If you can optimise for these within an exercise protocol you are going to get the best results you can probably get. And if you have been doing this for a long enough period of time with some consistency for several years, it probably doesn’t matter if you miss a workout. Even if you don’t workout for 2-3 weeks it’s unlikely you will start to lose muscle mass or physical capability (unless you’re bed ridden). You may be even stronger when you come to workout on week 3 or 4.
I don’t say this to discourage you from training weekly, twice weekly or more, I’m just reinforcing the notion that you should arrange your workouts around your life rather than your life around your workouts, as Dr Doug McGuff drummed into me here. Sometimes life can get a bit crazy and you’ll go through some real stressful shit that makes you feel like you’re stuck in a disorganised mess for a few weeks. Don’t worry, it’s probably going to do little, if almost nothing, to your gainz ;-).
8. Strong beliefs loosely held
Legendary Silicon Valley entrepreneur and investor, Marc Andreessen, has a unique mindset: “strong beliefs loosely held”. In other words, it’s important to develop strong views as opposed to following the general consensus, but some people can take this too far. In reality, we’re wrong about a lot of things and chances are a lot of your theories and beliefs are wrong so once the evidence presents itself one should be open to changing their mind on a dime.
Throughout my training career, I’ve been guilty of being dogmatic about new ideas. It started with the Spartan Health Regimen and it persisted with Body By Science and more recently, high-fat low-carb diets and the carbohydrate-insulin model. Body By Science is a wonderful book and my favourite health and fitness book of all time, but I took some of the concepts and theories too far and developed a strong belief around minimising training volume and frequency to facilitate continuous improvement. This concept maybe true but the point is that I closed my mind to alternative view points and this stalled my learning.
I’ve since become far more receptive to alternative approaches to high intensity training, resistance training and exercise in general in order to continue to develop my knowledge of health and fitness. For example, I’ve experimented with increased workout frequency even though I don’t think that it will make me any more muscular, but I was willing to put that belief to the test in the face of the most recent scientific evidence.
9. Multiple sets are okay
High intensity training is typically performed with a single-set-to-failure (SSTF) for each exercise in a given routine. Despite claims to the contrary, I believe that, if performed to momentary-muscular-failure (MMF), one set is as effective as any number of sets. This is a common view in the HIT community.
To measure my progress accurately, I will default to a SSTF but if I don’t feel like I gave a great enough effort or really hit failure, I don’t mind throwing in another set to failure, and I don’t get concerned about it. I’ll just note it down and move on to the next exercise. Again, in the past, I was militant about doing a SSTF and no more. If I failed to reach MMF and inroad for 5-10 seconds, I thought I had wasted my opportunity and had a sub-optimal workout. This is simply not true based on the current evidence. Whilst you should strive to achieve MMF, if once in a while you fall short and feel like throwing in a second set, go for it.
10. Less volume works too
As I’ve increased my strength, I have found that the first couple of big moves in any routine will practically destroy me. This assumes I’m training to momentary-muscular-failure with smooth form. A set of chins performed to failure with excellent form followed by a set of push-ups using the same protocol leaves me heavily fatigued.
I tried experimenting with a longer routine with Drew Baye’s Zelus workout, but as soon as I had completed it once, I found I had to abbreviate it immediately in order to “bring it” on every exercise within the routine, otherwise I’d just give up before failure. I find this particularly difficult with bodyweight workouts, where some exercises such as bodyweight squats require more “grit” and suffering before one reaches failure. A leg press on the other hand, can deliver a more potent and focused stimulus that shortens the exercise window and makes failure easier to achieve, at least for me.
11. I need structure
During the month of November, I participated in an N=1 push-up challenge. I was meant to perform 100 push-ups and take freezing cold showers every day for 30 days. I deviated from the protocol a little (spent a few days in Edinburgh where I did not adhere to protocol), but overall I complied 90% of the time.
I did not expect to see any “gainz’ from the push-ups or anything like that. It was more of a fun experiment to see how many push-ups I would be able to do by the end. At the start of the challenge I could perform 25-35 push-ups in my first set to failure. I can now exceed 50 easily and my best is 57. These are not HIT push-ups but faster more military style push-ups.
During this challenge, I reduced my full-body HIT workout to once per week for convenience and recovery. On one particular day, I went to the gym to train full-body. I’d been deliberately lax on tracking and structuring my full-body workout performance during the push-up challenge. This wasn’t for any real reason other than the cognitive load was getting to be too much for me. On this day, and in line with this habit, I did not track or structure my workout beforehand. Instead, I just decided I’d do a pull-push-pull-push-random stuff-random stuff (maybe abs):
- Chin-up
- Push-up
- Inverted row (2 sets)
- Overhead press (2 sets – drop set)
- Wall sits
- Bodyweight squat
- Pec Deck
- Hip Thrust (Not-to-failure)
- Leg raises (Not-to-failure)
I romanticised about going into the gym and executing maximum intensity on every set. I fell short of this expectation after only my second set. I had no set end point to my workout and the niggling feeling in my head that said “when is this workout going to end?” during the hardest part of every set caused me to give up too soon. I find that I train most effectively, when I know my goals, my exact training program, and most importantly, the end point. If I know I only have 1 or 2 exercises remaining in a workout, I’m far more likely to give the current exercise everything I have, and thus perform a more productive and disciplined workout.
Summary:
- Cadence doesn’t matter. Great form and smooth turnarounds do.
- Don’t be rigid. Experiment with volume and frequency. Find what works for you.
- Don’t be afraid to do more if you want. Play sport, be active. Intensity is on a spectrum. Just don’t be stupid.
- Move a lot. HIT will take care of most things, but frequent movement is important for overall health and physical capability.
- Bodyweight, free-weights and machines pretty much deliver the same results. Choose the method that is most convenient and enjoyable for you.
- Track your workouts but don’t get obsessed. Take a long term view. There are too many factors which affect performance from workout-to-workout.
- It’s not the end of the world if you miss a session. You won’t lose muscle. They won’t just fall off.
- Stay open minded. Be prepared to question your strongly held beliefs when new evidence presents itself.
- Multiple sets are okay. High effort is the main goal and whether this is done in one or two sets, it doesn’t really matter. It’s just easier to track with one set.
- If like me, a long routine (5+ exercises) is too much for you, abbreviate it and consider increasing the frequency. I currently train twice per week.
- If you’re like me and occasionally dread the intensity of HIT, you may want to ensure you’ve pre-planned an end point to your workout ahead of time to ensure you deliver your best performance.

My thoughts are at https://medium.com/@chrishighcock/my-philosophy-of-resistance-training-158bea8b6b9a Thanks for the shout out.
Pretty much the same, only that I am doing a lot more TSC exercises, squat, deadlifts, shoulders. I find that I can “hit”certain muscles better, and also that my muscles are firmer after them.
Also, I have studied a lot about breathing, and found some exercises for producing nitric oxide, and they are just enough for some movement during the day. Also, great for recovery.
For recovery, it takes 3-4 days to fully recover from HIT, but I just listen to my body, how it behaves during some movemebta. When I do them with ease, I do HIT that or the following day.
For the end, if you want to experiment with higher frequency, I read great article on t-nation several years before. It said, that you do pushups, lunges, and pullups, increasing reps every day by one. And it worked awesome for mass, also for resucing sone fat. But, after 25 days, some pains would start to appear in my elbow. I should do some easier variations. I think it’s called PLP, you should check that out.
Great work Lawrence!
Hey Lawrence, IMO this is The Best post of your “personal experiense” series so far :)))) Really, really liked it! My personal experience coinsides – 100%. I have only two small side comments:
1. I really do not like the “pistol” or one legged squats and overall unilateral exercises for the legs in general…but consider this a rather personal view and prefference;
2. Do not wait to move next to a proper gym, but start your own with a great equipment (like ARX perhaps)! 🙂 Seems to me, that with such tools, there is still a big difference in exercise preformance yet to be explored. Now, that I’ve tried the ARX personally, I got myself thinking about how significant difference there is between hitting failure after being intially fatigued with a weight/body weight (by moving intentionally slow and smooth) compared to – giving your organic effort right from the start of a set ( ex. an ARX set). It is by far more organic to all the people (my long time trained self included 🙂 ), to simply “push/pull – resist”, than to withhold ones self initially and then “suck it up” at the end of the set, after being well fatigued and in pain and in the same time to stare just at a wall for example… When you have the right instrument, then you will never really “dread” the intensity of effort and failure(no such a term there). You will actually be involved into crushing yourself much, much more readily. So weights – bodyweght – traditional machines does not matter, BUT some other type of machines may matter 😉
And like I noted in previous post – once and for all, the high velocity training advocates, who state, that pushing harder – moving faster is much more natural, will be finally put to rest, as they will be able to push as much as they want, but will still be saved form moving too fast and using momentum…for their own sake. F=M x A(constant) 😀
And by the way – Stop looking in Youtube for a porper exercise form videos…You obviously can produce ones of yoursef, showing and offering a great quality! :)))
Very good job – Cheers!
Hey Lawrence, great article, I recently starting training superslow and have found myself evolving to many of the points you make. I’m 51 now and looked for those who were successful in long term sustainable training because I love to train. Wanted to ask your thoughts on Richard Winnett write up on it here: http://ageless-athletes.com/training_update.php#continue … he’s 72 and trains 4x a week. Love HIT, but I do want to be in the gym more than once a week and wanted to give this a go. Thanks!
I love that I have come to many of the same conclusions you have through my own experiments with HIT. I have some additional “hacks” I’ve been using that I thought you might appreciate.
– While the mode of training (BW, weights, machines, etc.) doesn’t matter for physical benefits it matters a whole lot for psychological performance.
I tried doing HIT with just calisthenics once or twice a week for a year. I found that even if there was some benefit, I always felt discouraged by my performance. It sucks royally when you can’t do a pull up! Even starting with easier progressions, you have to mentally be in the game too. Once I switched to a dumbbell only routine, my consistency in meeting and exceeding my goals soared. Adherence trumps ease of use when it comes to this.
– Stop trying to use reps as a measure of progress – focus on adding small weights and moving to failure.
Like you, I also found it super discouraging if when I was tracking my reps/TUL if I didn’t go up every workout. Try as I might to be “rational” about it and remind myself about the long game, I found that psychologically I was nervous and discouraged if I wasn’t seeing those #’s go up. My solution? Just stop caring about that as a measure of progress. Instead, I started adding 1-2.5 lbs. a workout, keeping the weight used the same for every movement. BOOM, adherence increased. The way I see it is that if I go up 1 lb. per workout, twice a week for a year, I’m 100 lbs. stronger and tracking progress is easy.
Cool post! Thanks for sharing this 🙂
Thanks for the kind words Kamen! 🙂
One observation I’d add Lawrence: following the recent podacst with Brad, I thought I would experiment with the relatively faster 1 second/ 1 second cadence he advocates – but of course still smooth and in control (no explosive moves), minimising momentum. I’m a bodyweight resistance guy (to momentary muscular failure on every set), and after trying this faster cadence once, I found it a real game-changer. The faster cadence made the whole workout hugely more enjoyable for me, but weirdly I also found I was working harder, as I seem to be able to push myself harder at the end of the set for those last few painful reps.. The lactic acid burn seems to become more bearable.. And then I found myself wanting to do another set for every single exercise – and on one day actually feeling the desire to do 3 sets on a few exercises! I have looked in to what the hell is going on here, and I think it is what bodybuilders call the ‘pump’: ie lower load sets (bodyweight only in my case) performed at quite a fast cadence.
There seems to be some evidence that it drives metabolites into the muscles and builds sarcoplasmic volume (not necessarily more effective for the muscle fibres themselves though) – and this ‘pump’ seems to really get the endorphins flowing so you just want to push harder and do a bit more volume. A welcome change from the usual dread I used to have before going into a much slower cadence routine.. I may be mistaken, but my gains do seem to have finally become a bit more noticeable – at least it’s clear to see the effect of the ‘pump’ during the session itself, which I believe has some carry-over into the recovery phase. I’ve found myself completely switching over to this faster cadence style of training now for the next 2 months. Milking it whilst it works! I will probably then switch back to my normal 3/3 – 5/5 cadence after that just to switch it up again.
Has anyone else experimented with incorporating a ‘pump’ style of training into their HIT routines? I’d love to hear what Doug would make of this ‘pump training’ as the mainstay of one’s approach (as opposed to just a temporary deviation from a much slower cadence)!
One other thing I was going to mention: it might be worth exploring Lawrence what we all agree actually turns resistance exercise into ‘HIT’? As you say cadence, volume/ sets, frequency, exercise modality, load/weight – and also rest periods – can all be varied from very low to relatively high within the HIT framework, so what then makes it actually HIT as opposed to some other form of resistance exercise protocol? My answer to this is that the only thing that really determines whether it is HIT or not is whether EVERY set is taken to momentary muscular failure with each rep being performed in a smooth/ controlled fashion, minimising the effect of momentum. To me, that is the only reason that for example Brad Schoenfeld’s approach cannot be defined as HIT. For example, I currently am varying all of the above variables: ie experimenting with a relatively fast 1/1/ tempo, 2 or 3 sets of 8 or 9 exercises (but within a 45 mins workout), 3 times per week, low load (bodyweight only), short rest periods, but I still class it as being HIT since I always perform every set in a controlled manner to MMF. Although some might say this volume/ frequency is excessive: it seems to work for me in that I look forward to and enjoy it and do not seem to experience noticeable symptoms of overtraining. I think because I have dialled down the load variable – this facilitates a higher volume/ frequency – which is what I want. What are your thoughts on what are the essential aspects of resistance exercise in order for it to qualify as being ‘HIT’?
Great article Lawrence . I’ve come to many of the same conclusions that you have with regards to training . I’m currently training on a split routine once every 3 to 4 days doing a torso workout or upper body on the first followed by a leg workout on the second . The main reason i do this is because after training legs or even upper body for that matter it would be very hard to do justice to my legs or vice versa . It seems to me that many people want to find excuses to train more often then once or twice a week for whatever their reasons may be . I feel that training more than twice a week is unnecessary especially if one trains with a high level of effort / intensity . One must also keep in mind the crucial issue of wear and tear / cumulative damage on the body which increased training sessions along with the daily grind of life will bring .
Lawrence,
Is the “microtear” theory of muscle growth legit, or is it just bro-science? I wonder if any of your guests have addressed this topic?
I grew up with the idea that resistance training works because lifting creates microtears in the muscle fibers and in response, the body grows the muscle back bigger/stronger. I think this is still the dominant theory amongst most weightlifters.
On the other hand, we in the HIT community talk about going to muscle failure, causing the muscle to fatigue. The way I understand muscular fatigue is that it is a metabolic process, i.e. the energetic chemicals in the muscles decrease while the waste products increase. And then the body takes this as a signal to grow/strengthen the muscle.
These two theories seem very different and I’ve never really heard anybody in HIT compare and contrast them.
Interesting theory Nathan – however if this ‘metabolic’ theory was the whole story then going into workouts fasted would produce clear benefits in terms of hypertrophy, which has not been shown to date. That said, I do tend to workout fasted for other health benefits related to glycogen turnover, but unfortunately improved gains are not one of them!
Rob, I’m not necessarily endorsing the metabolic fatigue theory, and I may not be describing it accurately. I’m just saying that something like it is the dominant theory of hypertrophy in HIT circles, not the microtear theory.
Can you point me to discussions in the HIT community based on the microtear theory?
Hi Nathan, just off the top of my head the very first words I ever read relating to HIT was Doug’s quote from Body By Science as referenced in Tim Ferriss’s 4 Hour Body where Doug is putting the case for resting 1 week between workouts – likening the muscle damage to the repair that needs to happen after an eye injury. Ground breaking stuff at the time – I’m sure you know what I mean Lawrence?!
Problem is though when you hit your mid 40s the thing that doesn’t repair so quickly is the tendons and cartilage – but I have it on good authority (Chris Masterjohn) that taking 12g of collagen powder + vitamin C before my workout will help with that – so far so good. Also taking regular 1-2 week breaks from training. Unless you happen to be Ted Naiman of course…
I agree … to visualize how long it takes to put on muscle Doug has asked his readers to compare a pound of hamburger to how slowly a skin wound takes to heal. Something like that anyway.
What I’m saying is that the SIGNAL for muscle growth in the context of lifting is unclear. Is the SIGNAL structural microtearing of the muscle, is it metabolic fatigue, is it a combination of the two, or are other factors in play as well?
I’m interested in this question because I think it gets to the heart of the optimum volume question. My sense is that if microtearing is signalling muscle growth, it suggests a higher optimum volume than if metabolic fatigue is the signal.
Hey Lawrence,
this is an amazing article as i know almost every of the concerns regarding HIT.
Unfortunately, this made me stopping HIT and going back to conventional lifting, again. But now, after a few months i feel some pain all over my body (mostly knee and shoulders). I think of going back to HIT again (while I’m setting up my first home gym) – and your tips help a lot to find my way back…Thanks for that! 🙂
Re: #11 “Dread” … I’ve found that increasing my frequency from once/wk to twice/wk has almost completely eliminated dread. It has become more like a job I have to get done without question. My intensity has actually increased a bit as well.
Great article, thanks for sharing your experience but you had previous lifting experience before doing HIT and most likely already built some mass and definition. I’m doing HIT myself but I’m still skeptik as using HIT for a beginner to build strength and mass. All the dudes I’m seeing over the internet have prior bodybuilding experience, therefore it’s not clear whether they sculpted their body with HIT alone. Anyway, time will tell !
Hi Lawrence,
I wonder if you could post a follow-up to this post, I know it’s been a few years, wondering if you’re still doing Project Kratos-style workouts? For myself, I came upon Project Kratos around 2014 after a bad martial arts hip injury and haven’t given it up yet. A couple of preferences/things I’ve come up with:
1) I do pike pushups more horizontally than vertically – I brace my feet against a wall at the bottom and then push through the hip to apply variable resistance to the shoulders and triceps.. this takes away any headache/pressure issues from being partially inverted (like half or full handstand PU) and allows me to push my triceps harder.
2) I extend my legs a bit more and only have my heels on the floor when doing hip raises – this isolates the hamstring and makes the exercise much harder (especially doing 10/10 cadence).
3) Cadence does matter (for me). I can’t do 5/5 pullups because of shoulder pain, but 10/10 is perfect. I actually do 10/10 (with holds at the contracted position) for all of my movements.
4) I started using bands for hip belt squats and pushups, as well as stiff-legged deadlifts (wrapping the band across the back rather than pulling with the arms).I generally put towels between my back and band and hands and bands for comfort. I know bands (I use the heavy loop bands) get a bad rap, but I find that the band acts like a variable resistance machine (a very cheap, portable one) and works very well to add extra pressure at the top of the pressing movement (i.e. pushups can get better tricep involvement and squats can get better lower quad involvement). I find it hits my lower back just as well as using a Roman chair/hyperextension bench (which I find uncomfortable). I love 10/10/10 hip-belt squats using an exercise band. Occasionally I’ll add some extra weight with light dumbbells resting on the hips.
5) I always do a split routine because a) I’ve always had horrible recovery (and I’m now 46) and b) a full-body routine just takes too much out of me and I need my energy for other things as well. I end up doing about 3 days / week (usually Tuesday/Thursday/Saturday) with a lower / upper split, and upper is further split into an A/B, so upper exercises will happen about every 10 days, lower every 5. This gives me enough volume and variety to keep even my poor recovery in check.
