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

The purpose of a warm-up before exercise is primarily to prepare the body for physical activity and reduce the risk of injury. During a warm-up, the body gradually increases its heart rate, circulation, and muscle temperature, which helps to enhance overall physical performance. This process also improves the elasticity of muscles and tendons, making them less prone to strains or sprains during more intense activities. Furthermore, a warm-up helps increase the production of synovial fluid, which lubricates the joints, thereby reducing friction and the likelihood of injury.

While increasing flexibility and reducing fatigue, enhancing strength and muscle growth, and providing mental clarity are beneficial aspects of exercise routines, they are not the primary functions of a warm-up. The focus of this phase is about easing the body into more strenuous activities and ensuring that all physiological systems are ready for the demands of the upcoming exercise.
