The Interference Effect and Hypertrophy in Concurrent Training

Today’s episode begins with an exciting announcement about the forthcoming Black Friday Sale for the MASS Research Review, which extends from November 22 to November 29. After that, Greg shares a Road to the Stage update, and Eric takes a sharp turn onto the Road to Athens. That’s followed by Feats of Strength, and a Tech Support segment sharing MacroFactor reminders and updates related to the knowledge base, food database expansion, and the new public roadmap. Next, Greg provides an in-depth review of the literature related to cooling gloves and performance, and Eric gives some contextualized clarifications about low-calorie diets, age-related protein considerations, and positive aspects of cardio. Finally, Greg answers some listener questions, and Eric closes out the show by issuing a sobering warning about the grave consequences of Fat Bear Week.
