After being very interested in interval training especially vs steady-state training for years, this is absolutely the best presentation on the subject I've ever seen. I'm a personal trainer and what's amazing is that most of the fitness industry (1) doesn't understand or perform intervals as they apply to energy systems and (2) thinks the only point of intervals is to bring you to near-death (not literally) efforts because customers believe they've only really worked out if they're 100% exhausted (in essence the customers and their understandable lack of knowledge are leading the workouts rather than the fitness professionals). This is the point of most spin "interval" workouts as well as rowing in "Orange Theory" and other group fitness-based businesses e.g. Barry's Bootcamp. The number 1 thing they don't understand is rest. I've done Peleton spin classes with 8 entire Tabata rounds i.e. 64 work intervals in 45 minutes. Or ones where it's just all-out effort followed by supposedly greater all-out effort. I guess it means they're almost entirely aerobic (but they don't understand that) which maybe is okay if you do it once a week but doing all-out "interval" spin or other studio classes 5 times a week is a recipe for overtraining. I think your fitness will either plateau or get worse. Anyway, despite my digression, if you want to understand the nuances and details of interval training, this is the best reference I've come upon since I became interested in the science of interval training years ago.
