Carbohydrates play a vital role in sustaining energy during workouts by serving as the primary fuel source for the body. They are broken down into glucose, which is used by muscles for immediate energy during high-intensity activities. Consuming an adequate amount of carbohydrates before and after workouts helps replenish glycogen stores, supporting prolonged physical performance and effective recovery. Proper carbohydrate intake also helps maintain blood sugar levels, stabilizing energy and enhancing overall workout efficiency and performance.
