Setup
- Stand with your feet shoulder-width apart and a slight bend in your knees.
- Engage your core and maintain a neutral spine with your arms relaxed at your sides.
- Fix your gaze forward to begin in a stable, balanced position.
How to do it
- Rotate your torso to one side while reaching the same-side arm up and diagonally backward toward the ceiling behind you.
- Follow your hand with your eyes to encourage full rotation through the thoracic spine and neck.
- Exhale as you reach the peak of the rotation, then inhale as you return to the starting position with control.
- Immediately repeat the movement on the opposite side in a fluid, alternating pattern.
Form checklist
- Keep your hips facing forward as much as possible to isolate the rotation in your mid-back and obliques.
- Avoid excessively arching your lower back; focus on twisting rather than leaning back.
- Maintain a soft bend in the knees to stay grounded and protect the joints.
- Ensure the movement is driven by your core muscles rather than swinging your arms with momentum.
Pro tips
- Imagine 'wringing out' your torso like a towel to maximize the mind-muscle connection with your obliques.
- Reach as far back as your mobility allows to increase the active stretch on the anterior chain and chest.
Make it harder
- Hold a light dumbbell or a small medicine ball to add resistance to the rotational phase.
- Slow down the tempo significantly, holding the peak reach for 2-3 seconds to increase time under tension.
