Place dip belt around waist. Kneel as close as possible to low pulley or lever and attach hook to dip belt in front between legs. Step up and grasp parallel bars with hands facing inward. Lift legs off of steps or floor.
Pull body up until elbow are to sides. Lower body until arms and shoulders are fully extended. Repeat.
This particular apparatus could arguably be referred to as lever machine since dip belt attaches to lever arm, although relatively free movement between lever and dip belt offers qualities similar to cable machine. If weight bottoms out at bottom of movement, attach cable on chain links nearer ends of dip belt.
