The significance of pre-workout nutrition lies in providing the necessary energy and nutrients to optimize performance during exercise. Consuming a meal or snack rich in carbohydrates and protein around 30-90 minutes before a workout can enhance endurance, strength, and overall workout quality. Proper pre-workout nutrition helps in sustaining energy levels, preventing fatigue, and minimizing muscle breakdown. Additionally, it prepares the body for physical demands, improving focus and motivation during sessions.
