Episode 42: Alex Harrison on Concurrent Training (Part 2) and HIIT "High Intensity Interval Training"

Written By Zachary Greenwald

Alex Harrison, Science Consultant of Renaissance Periodization, joins us again to discuss Concurrent Training. Alex references the graph below, from the symposium review “Concurrent exercise training: do opposites distract?” by Coffey and Hawley, to explain the interference effect for both trained, and untrained populations.

Our topic then turns to HIIT “High Intensity Interval Training” for both endurance athletes and for CrossFit athletes. We dive into the physiology behind improving VO2 Max and discuss, at greater length, frequency and pacing considerations for this style of training.
