Post-workout nutrition refers to the consumption of specific foods or beverages after exercise to aid recovery. It is vital because it helps replenish glycogen stores, repair muscle tissue, and reduce soreness. Ideally, a combination of carbohydrates and protein should be consumed within 30-60 minutes post-exercise to maximize recovery benefits. This nutritional strategy not only enhances performance in subsequent workouts but also supports long-term fitness goals by facilitating quicker recovery and muscle adaptation.
