This is better than doing a 1000 sit ups!

This health and fitness video of Wesley Virgin shows you the proper way of exercising your abdominal muscles. Scientifically speaking, the traditional sit up exercise put to much stress on your back because of its ninety-degree angular movements. To avoid back problems,Wesley recommends this exercise that limits the movement of your back and combine it  with leg movements to compensate for the loss of back movements.

Other abdominal exercises like standing toe-touch, the plow, back bends, and hurdler stretch are considered less effective because of  unnecessary movements that cause stress on your back.

Other recommended abdominal exercises from the American College of Sports Medicine are standing cat-stretch, knee to chest, and seated toe-touch. You must not over-arch your back when performing these exercises.
