- Start in a plank position with a glider underneath your right hand.
- Engage your core as you lower down into a push-up with control. As you lower your body, simultaneously extend your right arm out in front of you. Lower down as far as you can go without losing your form. Be sure to keep your back flat.
- With control, push your body up as you simultaneously pull your right arm back in so that it's directly underneath your shoulder.
- This counts as one rep.
