Even a hard weightlifting session only uses up about 40% of your muscle sugar stores.

Glycogen depletion during resistance training is negligible in non-fasted individuals performing ≤10 sets per muscle group per session.

Even after a really tough weightlifting session, your muscles don’t run out of fuel fast enough to slow you down, and they can refill just fine even if you don’t eat carbs for a while.

Changing the weight you lift during a workout burns more muscle sugar than lifting the same weight the whole time.

After a weightlifting workout, the main leg muscle loses a lot of its stored sugar energy—about 21% on average—which can make you feel tired and affect how well you do in your next workout.
