Setup
- Lie prone on the floor with your legs extended and the tops of your feet flat.
- Place your hands flat on the mat directly under your shoulders with elbows tucked close to your ribs.
- Engage your glutes and core to stabilize your pelvis and protect your lower back.
How to do it
- Exhale as you press through your palms to lift your chest into a Cobra position, keeping your hips in contact with or very close to the floor.
- While holding the upward position, rotate your head and torso to look over your left shoulder, feeling the stretch across your right chest and anterior deltoid.
- Inhale to return to the center Cobra position, then exhale as you rotate to look over your right shoulder.
- Lower your chest back to the starting position with control to complete the rep.
Form checklist
- Keep your shoulders depressed and pulled away from your ears throughout the movement.
- Maintain a slight bend in the elbows to avoid locking the joints.
- Ensure the rotation comes from the thoracic spine (mid-back) rather than just twisting the neck.
- Keep your glutes squeezed to prevent excessive pinching in the lumbar spine.
Pro tips
- Push the floor away actively with the hand opposite the direction you are turning to maximize the stretch in the pectoral muscles.
- Focus on 'lengthening' your spine toward the ceiling before you begin the rotation to create space between the vertebrae.
Make it harder
- Hold the rotated position for 5 seconds while taking deep diaphragmatic breaths to deepen the myofascial release.
- Transition into an Upward Facing Dog by lifting your thighs and knees off the floor for increased core and arm engagement.
