Setup
- Place the foam roller horizontally on the floor.
- Lie back so the roller is positioned across your upper back, at the level of your shoulder blades.
- Bend your knees, place your feet flat on the floor, and support your head gently with your hands to avoid neck strain.
How to do it
- Lift your hips slightly off the ground to shift your body weight onto the foam roller.
- Slowly rotate your torso to one side, shifting your weight onto the trapezius muscle of that shoulder.
- Exhale as you rotate and apply pressure, then inhale as you return to the center and rotate to the opposite side.
- Perform the movement with a slow, controlled tempo, spending about 3-5 seconds per rotation.
Form checklist
- Keep your elbows tucked in slightly to move the shoulder blades apart and better reach the traps.
- Avoid rolling directly onto the cervical spine (neck) or the lumbar spine (lower back).
- Keep your core engaged to stabilize your torso while your hips are elevated.
- Ensure your head remains supported by your hands to prevent neck fatigue.
Pro tips
- When you find a particularly tight spot or 'trigger point,' hold the rotation on that side and take three deep breaths to encourage the muscle to release.
- Focus on 'melting' your upper back over the roller to maximize the depth of the massage and the thoracic stretch.
Make it harder
- Cross your arms tightly over your chest to further protract the shoulder blades, allowing the roller to reach deeper into the rhomboids and mid-traps.
- Lift your hips higher off the floor to increase the downward pressure and intensity of the massage.
