The dietary component critical for maintaining energy levels during workouts is carbohydrates. Carbohydrates serve as the body's primary source of fuel, especially during high-intensity exercise. They are stored as glycogen in the muscles and liver, providing the necessary energy for sustained physical performance. Consuming an adequate amount of carbohydrates before and during exercise can enhance endurance, delay fatigue, and improve overall athletic performance. Furthermore, post-exercise carbohydrate intake is essential for replenishing glycogen stores, supporting recovery, and preparing the body for future workouts.
