Warming up and cooling down are essential components of an effective exercise routine. Warming up prepares the body for physical activity by increasing heart rate, improving blood flow to muscles, and enhancing joint mobility, reducing the risk of injury. Cooling down helps the body transition back to a resting state, preventing blood pooling in the extremities and promoting recovery. Both processes support overall performance and long-term health by minimizing soreness and promoting flexibility, which is crucial for future training sessions.
