1. Attach the suspension trainer to a sturdy object overhead, and lower the foot cradles to about knee height (you want your body to be in a straight line when you rest your feet in them).
2. Get into pushup position with your feet in the cradles and hands placed shoulder width on the floor.
3. Keeping your abs braced, lower your body until your chest is just above the floor and then push back up.
4. Now bend your hips and raise them into the air until your torso is vertical. Straighten your body again. That’s one rep.
