The importance of warm-up exercises before intense workouts lies in preparing the body for physical activity. Warming up increases blood flow to muscles, elevating heart rate and enhancing flexibility, which reduces the risk of injury. It also mentally prepares individuals for the workout ahead, helping to improve focus. A thorough warm-up routine can include dynamic stretches and light aerobic activities, ensuring that the body transitions smoothly from rest to exertion. This practice enhances performance and contributes to safer exercise sessions.
