Why Is Stretching Important?
Stretching is a key component to any exercise program. Stretching not only improves the flexibility of our muscles, but it helps increase the range of motion of our joints. When our muscles are more flexible, the body can perform activities and exercise with the correct form. This helps to prevent injury, as well. Some key things to remember when stretching: Warm-up first! Cold muscle don’t stretch effectively. Try to hold the stretch for at least 30 seconds. Stretching should be pain-free.
