- The Drive: Push off with your legs, then swing your back open, and finally pull the handle towards your abdomen.
- The Finish: Legs are extended, back is slightly reclined, and handle is at your abdomen.
- The Recovery: Extend arms forward, then pivot your hips forward, and finally bend your knees to slide back to the catch position.
