Anchor the suspension trainer at mid-length. Stand facing the anchor point holding the handles, lean back into a straight-arm plank position with feet hip-width apart.

1. Brace core and glutes to maintain a rigid plank.
2. Pull your chest toward the anchor with one arm.
3. Simultaneously extend the opposite arm out to the side like a clock hand.
4. Keep hips and shoulders square, resisting rotation.
5. Squeeze the upper back at the top of the movement.
6. Lower with control, bringing the extended arm back to center.
