The back press exercise strengthens your abdominal (stomach) muscles and improves spinal flexibility. Follow these steps to perform a back press:
Begin on all fours with your knees under your hips and your wrists under your shoulders. Keep your back straight and your neck in its natural position.
Press your back upward by tightening the muscles of your belly and buttocks. The top of your back will be rounded and your stomach area will be tight. (Imagine a Halloween cat with its back "up.")
Hold this position for 10 to 15 seconds. Return to starting position. Repeat the exercise 5 times.
