Push-UpMuscle: ChestOther: Shoulders, TricepsType: CompoundAs you kneel on the floor, place your hands directly below your shoulders, slightly wider than shoulder width apart. Straighten your arms as you walk your feet back behind you. Your toes should be on the floor so that your body is in a straight line from your feet to your head. Be sure that your head is in line with the neck and the upper back should be straight during the entire exercise. Pull in your abs and keep your midsection tight. From the starting position, inhale as you bend your elbows and lower the body to the floor. Once your chest is almost touching the floor, exhale as you press yourself up by straightening the elbows. For less intensity, perform the exercise with your knees on the floor.
