Nutrition plays a crucial role in the body's response to exercise, affecting energy levels, recovery, and performance. A well-balanced diet provides the necessary macronutrients, such as carbohydrates for energy, protein for muscle repair, and fats for sustained endurance. Adequate hydration is also essential for optimal performance and recovery. Furthermore, proper nutrition can influence metabolism and enhance overall fitness results. Ultimately, aligning dietary habits with exercise routines is vital for maximizing potential and achieving fitness goals.
