Stretching Guidelines

Most aerobic and strength training programs cause your muscles to tighten. Stretching can increase flexibility and range of motion, helping you in your day-to-day activities and in the other components of your exercise program. When stretching:

-Target major muscle groups. Focus on your calves, thighs, hips, lower back, neck and shoulders. Also stretch muscles and joints that you routinely use at work or play.
-Warm up first. Stretching muscles when they’re cold increases your risk of injury, including pulled muscles. Warm up by walking while gently pumping your arms, or do a favorite exercise at low intensity for five minutes. If you only have time to stretch once, do it after you exercise — when your muscles are warm.
-Hold each stretch for at least 30 seconds. It takes time to lengthen tissues safely. Hold your stretches for up to 60 seconds for a really tight muscle or problem area. Then repeat the stretch on the other side. For most muscle groups, a single stretch is usually sufficient.
-Don’t bounce. Bouncing as you stretch can cause small tears in the muscle. These tears leave scar tissue as the muscle heals, which tightens the muscle even further — making you less flexible and more prone to pain. -Focus on a pain-free stretch. Expect to feel tension while you’re stretching. If it hurts, you’ve gone too far. Back off to the point where you don’t feel pain, then hold the stretch.
-Relax and breathe freely. Don’t hold your breath.

As a general rule, stretch whenever you exercise. If you’re particularly tight, you might want to stretch every day or even twice a day. You may want to sign up for a class on yoga or tai chi, which can promote flexibility. Plus, you may stick with a program better if you’re in a class.
