Today’s episode begins with a discussion about the very predictable scandal that rocked Fat Bear Week. After that, Greg presents a segment about accommodating resistance (that is, training with bands and chains). Greg digs into the available research and explains why accommodating resistance is beneficial for power development and explosive muscle actions, while failing to meaningfully impact maximal strength. That’s followed by Eric’s segment that clears up some misconceptions about the actual net energy cost of exercise. He explores how physical activity impacts total daily energy expenditure, describes some key characteristics that influence inter-individual differences in the net energy cost of exercise, and explains why and how to estimate the net energy cost of exercise using a new tool developed by the Stronger By Science team.
