" Sitting for long periods of time stiffens your back, resulting in lower back pain. Stretching can prevent this pain, increase your range of motion and improve your posture. In the third video of WD&amp;#039;s flexibility series, fitness expert Angela Joyce prepped you for the backbend by using a stability ball for support. Once you&amp;#039;re comfortable with this position, try stabilizing yourself without the ball to both strengthen and stretch your back. Certified personal trainer Amy McCauley shows you how to do so in today&amp;#039;s video, demonstrating safety tips and proper form for executing an unassisted bridge, one of the most efficient exercises for increasing back flexibility. Follow her guidelines for fast results and check back every Monday, Wednesday and Friday at noon to learn more about how stretching can improve your flexibility.
