Secure a resistance band to an anchor at chest height. Sit sideways on a bench or ball with tall posture, gripping the band with both hands extended toward the anchor.

1. Rotate your torso away from the anchor while pulling the band diagonally across your body.
2. Extend arms fully toward your opposite hip, keeping elbows slightly bent.
3. Contract obliques at the end position.
4. Inhale and reverse the motion, resisting the band's pull back to start.
5. Maintain neutral spine throughout.
