Stretching is a form of physical exercise in which a specific muscle or tendon (or muscle group) is deliberately flexed or stretched in order to improve the muscle's felt elasticity and achieve comfortable muscle tone. The result is a feeling of increased muscle control, flexibility, and range of motion.
The takeaway. Whether you're new to exercise or a seasoned athlete, you can benefit from a regular stretching routine. By incorporating 5 to 10 minutes of dynamic and static stretches into your daily workout, you can increase your range of motion, improve your posture, and ease your mind.
Stretching first thing in the morning can relieve any tension or pain from sleeping the night before. It also helps increase your blood flow and prepares your body for the day ahead. Stretching before bed relaxes your muscles and helps prevent you from waking up with more pain.
Healthy adults should do flexibility exercises (stretches, yoga, or tai chi) for all major muscle-tendon groups—neck, shoulders, chest, trunk, lower back, hips, legs, and ankles—at least two to three times a week. For optimal results, you should spend a total of 60 seconds on each stretching exercise.
