Workouts are a terrible thing to waste. Muscles broken down from strenuous activity benefit from protein almost immediately after exercising, meaning the quicker you feed them, the sooner they begin rebuilding. During exercise, you burn through fuel stores in muscles and energy reserves in the liver. Replenishing these carbs is a critical step to being ready for tomorrow's workout. Two sources of calories offer one complete recovery. The calories from carbs refill depleted energy stores in muscles and the calories from protein help rebuild them. Gatorade Recover Chocolate Protein Shakes have 20g protein per bottle and contain high-quality whey and casein proteins.
