Muscles worked

Primary

  • Trapezius

Secondary

  • Abs
  • Lats
  • Obliques
  • Rhomboids

Equipment

  • Foam roller

Setup

  1. Place the foam roller horizontally on the floor.
  2. Lie back so the roller is positioned across your upper back, at the level of your shoulder blades.
  3. 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

  1. Lift your hips slightly off the ground to shift your body weight onto the foam roller.
  2. Slowly rotate your torso to one side, shifting your weight onto the trapezius muscle of that shoulder.
  3. Exhale as you rotate and apply pressure, then inhale as you return to the center and rotate to the opposite side.
  4. 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.
