Define warming up and types of warming up?

Warming up is a pre-exercise routine designed to prepare the body for physical activity by gradually increasing heart rate, blood flow, and muscle temperature. It typically consists of dynamic movements and stretches that mimic the activity to be performed. The two main types of warming up are general warm-ups, which involve light aerobic exercises like jogging or jumping jacks, and specific warm-ups, which focus on the movements and muscles specific to the upcoming activity, such as sport-specific drills. Both types help reduce the risk of injury and enhance performance.
