What is the purpose of a warm-up before exercise?

The purpose of a warm-up before exercise is fundamentally to prepare the body for physical activity. Warm-ups involve gradually increasing the body's core temperature, enhancing blood flow to the muscles, and improving joint mobility. This physiological preparation mitigates the risk of injury by ensuring that the muscles are more pliable and ready for the stresses of the forthcoming workout. Additionally, a proper warm-up can improve overall performance by allowing the body to transition smoothly into higher intensity movements and activities.

While increasing muscle strength, aiding in muscle recovery, and improving coordination can be beneficial side effects of a well-structured warm-up, these are not the primary objectives. The main goal remains to condition the body for the demands of exercise, ensuring both safety and efficacy in physical performance.
