You wouldn’t expect your car to just “take off” without giving it some time to warm up would you? You can’t expect your body to take off right away either. Take some time before your run or walk warm up your body. Warming up is different than stretching. Stretching is great after your workout to release any tension that has built up. Warm ups, on the other hand, are dynamic rather than static like stretching. In a dynamic movement, you do not hold the position as you would when you are stretching. Rather you move “through” the movement. Kind of like revving your car engine, this gives the body a chance to ease into movement rather than just slamming down on the gas pedal. Take a look at a sample warm up routine in the video below.
