Dietary adjustments that can improve energy levels during workouts involve ensuring adequate intake of carbohydrates and hydration. Carbohydrates serve as the primary fuel source for high-intensity exercise, and consuming complex carbs, like whole grains and fruits, can boost energy. Additionally, staying properly hydrated before and during workouts is critical, as dehydration can significantly impair performance and reduce endurance. Including consumables such as bananas or energy gels can also provide quick energy boosts during longer sessions.
