- Begin in plank position with the arms and body straight, shoulders over the wrists. Keep the core engaged. To modify, go down to your knees.
- Bend the elbows behind you and lower your chest to the floor. Keep your upper arms tight to your body so your elbows are against your ribs on both sides.
- Straighten the arms, coming back to plank position. This counts as one rep.
- Complete for a total of five reps if you're on your toes (as pictured) or 10 reps if you're modifying on your knees.
