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

The primary purpose of a warm-up before exercising is to prepare the body for physical activity. A proper warm-up raises the body's temperature, increases heart rate, and enhances blood flow to the muscles, making them more pliable and reducing the risk of injury. This physiological response helps to prepare the cardiovascular, muscular, and nervous systems for the demands of exercise.

Additionally, a warm-up often includes dynamic movements that can improve flexibility and range of motion, which can further enhance performance in a workout. By adjusting the body gradually to the intensity of the upcoming activity, a warm-up encourages better performance and more effective workouts. This preparation optimally primes both the mind and body for the activity ahead, fostering a safer and more effective exercise session.
