I do not recommend stretching a cold muscle. You will receive greater benefits in activating the muscles in which you are preparing to call on for your chosen form of exercise. Consider this as a “waking up” period for the muscles that need to stabilize or drive you in your workout.
If you have a specific tightness that you feel needs to be addressed prior to your workout, keep in mind the speed in which you will be performing your exercise. You don’t want to teach these muscles to lengthen in a “slow and controlled” environment during warm-up and then throw them into an environment that requires the movement to occur rapidly. Consider dynamic stretching as a safer form of preparation.
