Navigating Engineering Research Challenges

This week we’ve got a MONSTER episode in the form of a live Q&A episode with Dr. Helms and Dr. Trexler. The Good Doctors begin with a recap of the recent WNBF World Championships, followed by an insightful discussion about whether or not humans have a “factory error” in our design that promotes obesity. This is followed by a number of listeners’ questions about functional anatomy, exercise selection, the importance of the eccentric phase of a lift, factors impacting reps in reserve (RIR) accuracy, biceps contributions to back exercises, hypertrophy considerations for the deadlift exercise, mini-cuts, set-to-set fatigue, energy expenditure limits, “delayed” hypertrophy, how to tell if you’re a creatine nonresponder, and velocity-based training.

The MASS crew records Iron Culture LIVE on YouTube, every Monday night at 7pm eastern time. Be sure to join us for a future episode and say hello in the live chat!
