Setup
- Adjust the hip pad so the top edge sits just below your hip crease to allow for a full range of motion at the pelvis.
- Secure your feet firmly against the footplate and tuck your ankles securely under the padded rollers.
- Cross your arms over your chest or place your hands lightly behind your ears, keeping your elbows wide.
- Start with your body in a straight line from your heels to your head, engaging your core.
How to do it
- Inhale and slowly hinge forward at the hips, lowering your torso until you feel a deep stretch in your hamstrings while maintaining a flat back.
- Exhale and contract your glutes and hamstrings to lift your torso back up until your body forms a straight line.
- At the top of the movement, rotate your torso to one side by leading with your shoulder, keeping your hips square to the pad.
- Inhale as you rotate back to the center and lower your torso to begin the next rep, alternating the direction of the twist each time.
Form checklist
- Maintain a neutral spine throughout the movement; do not round your lower back during the descent.
- Avoid overextending or arching your back past the straight-line position at the top.
- Keep your hips pressed firmly into the pad to ensure the movement comes from the hip joint and thoracic spine.
- Ensure the rotation is controlled and driven by the obliques, not momentum.
Pro tips
- Squeeze your glutes hard at the top of the hinge before starting the twist to stabilize your pelvis and protect your lumbar spine.
- Focus on 'opening' your chest toward the side wall during the twist to maximize oblique engagement and thoracic mobility.
Make it harder
- Hold a weight plate or dumbbell against your chest to increase the resistance on the posterior chain and obliques.
- Perform the movement with a 3-second eccentric (lowering) phase and a 2-second pause at the peak of the rotation.
