Bring yourself to the ground directly behind, and facing away from, an indoor rower. Enter a high plank position with your hands directly under your shoulders. Carefully, place one foot at a time on the rower seat pad. With both feet securely onto of the seat pad and legs fully extended, proceed to bend at the hips driving them upwards and towards your shoulders. Exhale as you do so. Make sure to keep your core contracted throughout. You should finish in an inverted V position. Pause and slowly return to the start position, inhaling as you do so.
