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

The primary purpose of a warm-up before exercise is to prepare the body and prevent injury. A warm-up typically involves a gradual increase in heart rate and blood flow to the muscles, which helps to increase muscle temperature and flexibility. This physiological response enhances the body's ability to perform physical activities, making muscles and joints more pliable and less prone to strains or injuries during high-intensity movements.

Additionally, a proper warm-up primes the cardiovascular system, making it more efficient for the demands of upcoming exercise. It also helps in mentally preparing the individual for the workout ahead, creating a focus and readiness that can enhance performance. Overall, the warm-up serves as a crucial step in any workout routine, helping to facilitate better results while minimizing the risk of injury.
