Stretching may help you:
Be more flexible.
Feel more relaxed.
Improve posture.
You do not have to set aside a special time or place to stretch. At home or at work, stand up, push your arms toward the ceiling, and stretch. Stretch slowly and only enough to feel tightness—not until you feel pain. Hold the stretch, without bouncing, for about 30 seconds. Do not stretch cold muscles.
Yoga and tai chi are two types of stretching. They help you breathe deeply, relax, and get rid of stress.
Your local fitness center may offer yoga, tai chi, or other stretching classes. You may want to start with “gentle” classes, like those aimed at seniors.
