If you're lucky, you get plenty of cardio vascular exercise. Maybe you pound out three miles on the treadmill. You work your way through a series of weightlifting exercises. You even add some time on the stationary bike for good measure — and you smile with satisfaction that you made it through your workout. Nothing to do now but hit the shower.

Not so fast. Did you consider stretching those muscles that pulled you through your invigorating workout? Most aerobic and strength training programs inherently cause your muscles to contract and flex. For equal balance, pay attention to stretching those muscles after your workout.

Benefits of Stretching
Regular stretching is a powerful part of any exercise program.

• Stretching increases flexibility. Flexible muscles can improve your daily performance. Tasks such as lifting packages, bending to tie your shoes or hurrying to catch a bus become easier and less tiring.
• Stretching improves range of motion of your joints. Good range of motion keeps you in better balance, which will help keep you mobile and less prone to injury from falls — especially as you age.
• Stretching improves circulation. Stretching increases blood flow to your muscles. Improved circulation can speed recovery after muscle injuries.
• Stretching promotes better posture. Frequent stretching keeps your muscles from getting tight, allowing you to maintain proper posture and minimize aches and pains.
• Stretching can relieve stress. Stretching relaxes the tense muscles that often accompany stress.
• Stretching may help prevent injury. Preparing your muscles and joints for activity can protect you from injury, especially if your muscles or joints are tight.

• Target major muscle groups. When you're stretching, 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. Better yet, stretch after you exercise — when your muscles are warm and more receptive to stretching. One caveat: If you plan to stretch only after your workout, increase the intensity of the activity more slowly than you would if you had stretched your muscles before exercising.
• Hold each stretch for at least 30 seconds. It takes time to lengthen tissues safely. Hold your stretches for at least 30 seconds — and up to 60 seconds for a really tight muscle or problem area. That can seem like a long time, so keep an eye on the clock or your watch. Then repeat the stretch on the other side. For most muscle groups, a single stretch is often enough if you hold it long enough.
• 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 any pain, then hold the stretch.
• Relax and breathe freely. Don't hold your breath while you're stretching.
