People often stretch to prevent muscle sores and injuries, though a better way is to pump up your adrenaline. This can be done with jumping, or punching a body-bag. The Africans jump up and down, while chanting, for an adrenaline rush before hunting. This calms the muslces better than any streching can do. Please share your thoughts or opinions. Thank you.
