Pre-and post-workout snacks are significant because they replenish energy stores, support recovery, and enhance overall performance. Pre-workout snacks should include a balance of carbohydrates and protein to fuel exercise, while post-workout nutrition should focus on refueling glycogen stores and repairing muscle tissue, typically through carbohydrates and protein. Consuming these snacks at appropriate times helps optimize muscle recovery, improve subsequent performances, and maintain consistent energy levels during workouts.
