The Pushups On The Stability Ball exercise is superior to regular pushups because you engage many more muscles, including the critical core muscles. The exercise also helps to improve your balance. 1) Get on your knees and place hands a little less than shoulder width apart onto the stability ball. 2) Align hands at the nipple line with your feet hip width apart on your toes. Extend your arms to raise your body. Your trunk and hips should be in a straight line. Don't bow your back! 3) Lower your body 1-2 inches from the stability ball. 4) That is one repetition. The next time you work out, try this great exercise!
