High-intensity workouts lead to significant increases in enzymes and metabolic pathways that facilitate glycogen storage and prevent excess glucose from being converted into adipose tissue.

“Depleting one's glycogen actually takes some time. You know, if you do a couple sets of tricep extensions and some crunches, you're not depleting your glycogen. Glycogen depleting workouts are very high intensity. Generally they're less than an hour or so, but those are the sort that are going to lead to big increases in the kinds of enzymes and metabolic pathways that are going to repack glycogen and shuttle most things towards restorage of foods not into adipose tissue, not into fat, but taking glucose and making it into fuels that you can access later for more of that high intensity activity.”
