Warming up before exercising is crucial for preparing the body for physical activity. A proper warm-up increases blood flow to the muscles, elevates heart rate, and improves joint mobility, reducing the risk of injury. It also enhances muscle elasticity and prepares the nervous system for the demands of the workout. Incorporating dynamic stretches and movements gradually primed for the exercise type can optimize performance. Additionally, warming up mentally prepares individuals by focusing their attention and setting an intention for the workout session.
