The primary benefit of warm-up exercises is to prepare the body for physical activity, reducing the risk of injury. Warm-ups increase blood circulation to muscles, raising core temperature and flexibility. This readiness process enhances joint mobility and boosts performance by mentally preparing individuals for exercise. A good warm-up also activates the heart, increasing heart rate gradually, which minimizes the shock on the cardiovascular system. Incorporating dynamic stretches or light aerobic movements into the warm-up routine is key to achieving these benefits effectively.
