A warp-up is a brief 5-15 minute period of light exercise that comes before a workout or physical activity. This should involve a light callisthenic or low-intesity form of exercise and often involves stretching in the exercise. The purpose of a warm-up is to elevate your temperature and to increase blood flow to the muscles that will be used in your activity.
In the golf swing "The body works in an alternating pattern of stable segments connected by mobile joints. If this pattern is altered - dysfunction and compensation will occur." As first noted by Mike Boyle and Grey Cook.
The mobile parts of our body for a normal golf swing are: Ankles, Hips, Thoracic spine (upper body), Shoulders and Wrists.
