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.

  • That was one of the more interesting interviews that I’ve heard from you. The guest is obviously quite knowledgeable. Moreover, he has experience and fluency in a number of different realms: HIT, traditional S&C, olympic lifting, physical therapy, and academic biomechanics. That makes for some interesting insights.

    I really enjoyed hearing about the evolution of his business. I also enjoyed the discussion about different ways to work the glute. I have never hear anyone use the phrase hip “A-B-duction”, but it makes sense as a way of avoiding confusion.

    I imagine some squat advocates had their heads explode when the phrase “glutes aren’t firing” was uttered. However, his follow up comments show that he had a great deal of contextual understanding of the issues.
