Place both hands on the ground, shoulder width apart, and arms extended straight. Hips are open and legs are straight balancing on the toes. Lower the body by bending elbows while keeping core and buttocks engaged and forearms at a 90 degree angle to the floor. Once the chest makes contact with the ground, extend the arms and push up into the starting position. Ring push-ups: perform a push-up with a set of gymnastic rings (feet on the ground, hands on the rings).
