Glycogen Resynthesis Window
The glycogen resynthesis window is the post-exercise period when muscles refill glycogen faster. Carbs with protein help most when another hard session comes soon.
The glycogen resynthesis window is the elevated rate of muscle glycogen refill in the hours after glycogen-depleting exercise—carbs plus protein help, especially when the next hard session is within twenty-four hours. The window is wider than old thirty-minute myths but earlier fuel still aids back-to-back training.
Match carbs to session cost, not guilt.
Common questions
-
Is the glycogen window only thirty minutes?
Glycogen synthesis continues for many hours; the first few hours are simply efficient. Back-to-back hard days benefit most from prompt post-session carbs.
