Mistakes to avoid
Don't bounce. Using momentum to increase your stretch can activate the body's protective reflex, causing the muscles to contract instead of stretch, which can lead to small tears.
Don't stretch to the point of pain. While you may experience a little discomfort in an area that is tight, actual pain is your body's way of letting you know something is wrong.
Don't forget to breathe. Not only is oxygen exchange necessary for the muscle to respond in a beneficial way to a stretch, but holding your breath may temporarily increase blood pressure. Focus on inhaling as you get in position for the stretch and exhaling as you move into it. Keep your breathing slow and regular.
