The purpose of warming up before workouts is to prepare the body for physical activity and reduce the risk of injury. A proper warm-up gradually increases heart rate and blood flow to muscles, enhancing flexibility and joint mobility. This process helps to loosen up tight muscles and prepares them for more intense actions. Additionally, warming up mentally primes athletes for the workout ahead, fostering focus and motivation. Engaging in a routine warm-up can significantly improve performance and ensure a safer, more effective exercise session.
