Hi, this is Martin Snow of the Trinity Boxing Club in New York City for About.com, and today I’m going to teach you 3 variations of the push up.The Standard Push Up is the God-father of all body weight exercises. You are going to start on the ground, with your elbows in, hand shoulder width apart. Pull your belly button into your spine, keep your back rigid, and push yourself away from the floor slowly. Then pull yourself back into the floor, again slowly. Do this for 10 repetitions, slowly and controlled to start off your workout. In order to perform the standard push up correctly, always remember to keep your back straight as you push yourself up off the floor.Another variation of the standard push up is the wide hands push up. Bring your hands a little wider than shoulder width apart and perform it the same way you would the standard push up. Make sure your back is straight as you push yourself up off the floor. The wide hands push ups work every muscle in the body with an emphasis on the chest and arms.Another variation of the push up is the military push up. Keep your elbows in against your body. Your hands should be shoulder width apart and push yourself up off the floor. Keep your back rigid, and again push yourself away from the floor. Keep your elbows in against your body, that makes it more intense. Thank you for watching, for more information, go to About.com.
