Why is warm-up an important part of aerobic activity?
A warm-up helps your body prepare itself for exercise and reduces the chance of injury. The warm-up should be a combination of rhythmic exercise to raise the heart rate, core body and muscle temperature, and static stretching through a full range of motion. The stretches in the warm-up should be non-ballistic and include all of the major muscle groups. A lower backstretch should be performed before doing any lateral movement of the upper torso such as side bends.
