workout warm up part 1

Stretching and a warm-up are important to do before a workout because they prepare the body for physical activity. A proper warm-up increases blood flow to the muscles, which delivers oxygen and nutrients needed for energy production and also raises the body's temperature, making the muscles more pliable and less prone to injury. Stretching also helps to increase range of motion and flexibility in the joints and muscles, which can improve performance and decrease the risk of injury. Additionally, stretching can also help to reduce muscle tension and soreness after a workout. Together, a warm-up and stretching routine can help to prime the body for exercise, resulting in a safer and more effective workout.
