The best way to fuel your body before a workout involves consuming a balanced meal or snack that includes carbohydrates and protein. Carbohydrates provide essential energy for performance, while protein aids in muscle repair and recovery. Ideally, this pre-workout meal should be consumed about 1-3 hours before exercising, incorporating foods like whole grain toast with peanut butter, yogurt with fruit, or oatmeal. Staying hydrated is also crucial, as proper hydration supports overall exercise performance and prevents fatigue.
