Is stretching the same as warming up?
A No. They are two distinct activities. A warm-up is light exercise that involves moving the joints through the same motions used during a more intense activity; it increases body temperature so your metabolism works better when you’re exercising at high intensity. Stretching increases the movement capability of your joints, so you can move more easily with less risk of injury. It is best to stretch at the end of your aerobic or weight training workout, when your muscles are warm. Warmed muscles stretch better than cold ones and are less prone to injury.
