This episode is brought to you by ARXFit.com, ARX are the most innovative, efficient and effective all-in-one exercise machines I have ever seen. I was really impressed with my ARX workout. The intensity and adaptive resistance were unlike anything I’ve ever experienced. I love how the machine enables you to increase the negative load to fatigue target muscles more quickly and I love how the workouts are effortlessly quantified. The software tracks maximum force output, rate of work, total amount of work done and more in front of you on-screen, allowing you to compete with your pervious performance, to give you and your clients real-time motivation. As well as being utilised by many HIT trainers to deliver highly effective and efficient workouts to their clients, ARX comes highly recommended by world-class trainers and brands including Bulletproof, Tony Robbins, and Ben Greenfield Fitness.

This episode is brought to you by Bill DeSimone. Bill has appeared on the podcast twice and is one of my favourite personal trainers. Bill runs Optimal Exercise, a personal training studio based in central NJ, USA. Bill is incredibly knowledgeable about exercise, strength training, and in particular biomechanics and rehabilitation, and is the go-to guy for a lot of top HIT trainers like Dr Doug McGuff.
Bill is the author of Congruent exercise: How To Make Weight Training Easier On Your Joints. I loved this book and finished it in a few days. I learnt how to select safe and effective exercises and gained a better understanding of how to construct productive workouts. It gave me much more insight into exactly how the joints and muscle operate specific exercises, and does so in a very elegant manner. To pick up your copy of Congruent Exercise, head on over to Amazon.com, where you can buy a copy in print or on Kindle. The Kindle version contains links to various videos where Bill demonstrates the exercises, which being a visual learner, I found this particularly helpful.
Watch out for Bill’s next book: Joint-Friendly Fitness: Your Guide to the Optimal Exercise Program. Having seen a draft, I am very excited about this book and looking forward to talking to Bill to learn all about it. To connect with Bill and learn all about his upcoming book, product and services, go to optimalexercisenj.com

During the course of our conversation, Mark spoke in detail about ARX in action, though it’s a bit of a challenge to simply leave things to the imagination. That being the case, here’s a video that shows ARX in action.
QUESTIONS OF THE DAY: Have you tried using negative accentuated training in your routine? What were the results? Please let me know how it turned out in the comments at the bottom of this post.

Well, that interview was really Awesome! Thanks Lawrence and thanks Mark! I’d love to try ARX first hand! I have two questions to Mark:
1. Please, share ARX locations in Europe and continental Europe in particular, so I can more easily visit;
2. How “the second set” approach disqussed is compared to rest-pause in Mark’s opinion? In other words, what seems to be the “necessary” rest between sets (to prime the central system etc.) if one would like to try and shoot for the second set approach?
Thanks!
Glad you enjoyed the interview Kamen!
1. You can try ARX at Mint Fitness in Brighton UK or The Resistance Institute in Barcelona.
2. As for the second set approach, I’d recommend minimal rest between exercises of the first superset/circuit (15-30 seconds) and just a little bit longer between the first and second superset/circuit (60-90 seconds). So essentially, you’d do a typical big 3 or big 5 type of workout with minimal rest between sets, then, repeat the entire circuit one more time after at least a minute of rest. I’d recommend experimenting with this approach with 3 exercises initially (i.e. starting with 6 total working sets). Hope that helps! 🙂
Thanks Mark, sure helps! I’ll give it a fair try. As for ARX technology, me and my partners have a very serious discussion about bringing it to BG. I am already in touch with your staff, so if we figired it out, we’ll be proud to be your next location in EU 😀
Sounds great Kamen! Stay strong…ARX strong! 🙂
Great episode, lots of food for thought. I really liked Mark’s lack of hubris, no really sensational claims and what seems like genuine passion for benefiting public health and working with genetically average trainees. After listening and watching I’d be interested in giving the ARX a go, I might have a bit of work in Brighton at some point so would be interested in dropping in to Mint.
One little snippet that jumped out at me was Mark’s mention of core stability and isolation movements as an adjunct to the big compounds. For someone training at home without fancy equipment I’ve found the most efficient method is to do unilateral upper body exercises; overhead press and especially, heavy shrugs with a single dumbbell for example can really tax the obliques. Modifying a body weight squat into a “goblet” squat is a decent technique too in my experience.
Lastly, one clarification. Does Mark advocate doing two full body workouts per week each doing two sets of every exercise to failure? That would work out to potentially double the volume of say, Drew or Doug’s recommendation.
Oops, just read Mark’s other reply “big three” sounds doable with two sets. I fancy the recovery would be killer though!
The whole way the ARX works and what it allows and helps the user do, makes a great deal of sense. Maybe get to try one out someday.
I’m no exercise machine aficionado, but I was very impressed with ARX. The level of inroad and fatigue it can create is intense. Obviously one may have to be careful not to overtrain.
Hey Lawrence, not sure if this is the right place for this comment, but I actually made my plans for visiting Mint Fitness in Brighton and try their ARX machine in person. It will most probably be on 7th or 8th of Decmeber. Staying in London from 7.12.17 till 11.12.17 I already have almost everything aranged. So, in case that you happen to be somwhere in the vicinity… and have the time, I’ll be more than happy to meet you there in person 🙂
Nice one Kamen. Matt Nairn is a great guy and you’ll get he full ARX experience with him!
I would love to meet, but sadly I’m unable on those dates. I’m interviewing Shawn Baker MD on the Mon which is a few days after his appearance on Joe Rogan! Also interviewing Dr Wayne Westcott on the same day!!
Would love to meet in the future though. If you’re up for it, I’m at the Resistance Exercise Conference 9/10th March 2018, use coupon code corporatewarrior10 for 10% off ???????????????? I’m sure you’ve heard that already (a few times …) hahaha
…Either that or…when you decide to do your Booze vacation in Bulgaria…Ha ha. In the recent years a lot of Englishmen take this option ;D
In any case, I’ll share my experience with ARX afterwords!
