1. Begin in a high plank position with feet together, hands directly beneath the shoulders, and a ruck with the desired amount of weight secured to the back.

2. Lift the right hand off the ground and bring it to the right hip.

3. Keeping the left hand planted into the ground, rotate the torso to the right until the hips and feet are vertically stacked on top of each other.

4. When you've held for the desired duration, rotate the torso back to floor-facing and return the right hand to the ground.
