The best time to do flexibility exercises is when your muscles are already warm so they can stretch farther without tightness or pain. If youâre doing only stretching exercises, warm up with a few minutes of easy walking first to warm up your muscles.
Keep the following stretching tips in mind: 1  Start at the neck and work each muscle group down the body. 2  Stretch slowly and gently only to the point of mild tension, not to the point of pain. 3  Hold each stretch for 10 to 20 seconds. 4  Don't hold your breath. 5  Stretch for the same amount of time on each part of the body.
