Warm-up programs are structured activities designed to prepare the body for physical exercise or sports. They typically include light aerobic exercises, dynamic stretches, and mobility drills that increase heart rate, improve blood flow to muscles, and enhance flexibility. This preparation helps reduce the risk of injuries and improves overall performance during the main activity. These programs can vary based on the type of sport or exercise being performed. For example, a warm-up for running may include leg swings and high knees, while a warm-up for weightlifting might focus on lighter sets of the intended lifts. Proper warm-up routines are essential for athletes of all levels.
