Roll Thoracic Spine Lying On Floor

  • Isolation
  • Timed hold
  • Back
  • Lower legs
  • Upper legs

This self-myofascial release technique improves thoracic mobility and relieves tension in the upper back, specifically targeting the trapezius and latissimus dorsi. It helps counteract postural rounding and increases the range of motion for overhead movements.

Muscles worked

Primary

  • Erector spinae

Secondary

  • Glutes
  • Obliques
  • Quadriceps

Equipment

  • Foam roller

Setup

  1. Place a foam roller horizontally on the floor and sit in front of it with your knees bent and feet flat.
  2. Lean back so the roller is positioned just below your shoulder blades (mid-back).
  3. Support your head gently with your hands to avoid neck strain, or cross your arms over your chest to spread the shoulder blades.
  4. Engage your core to maintain a neutral lower back.

How to do it

  1. Lift your hips slightly off the floor, supporting your weight between your feet and the roller.
  2. Use your legs to push and pull your body slowly, rolling from the middle of your back to the top of your shoulders.
  3. Inhale deeply as you roll downward and exhale as you roll upward toward the neck.
  4. Move at a slow tempo, pausing for 20-30 seconds on any particularly tight or 'hot' spots.

Form checklist

  • Avoid rolling onto the lower back (lumbar spine) where there is no rib cage support.
  • Keep your chin tucked slightly toward your chest to protect the cervical spine.
  • Ensure your hips stay elevated but close to the floor to maintain control.
  • Keep your core braced to prevent the rib cage from flaring excessively.

Pro tips

  • To better target the lats, lean your torso slightly to one side (about 15-30 degrees) while rolling.
  • Hug yourself tightly to protract the scapulae; this exposes the muscle tissue of the mid-traps and rhomboids for deeper release.
  • Focus on 'melting' your muscles over the roller rather than tensing up against the pressure.

Make it harder

  • Extend your arms straight overhead while rolling to increase the stretch on the lats and the leverage on the thoracic spine.
  • Perform thoracic extensions: stop at a tight spot, drop your hips to the floor, and gently arch your upper back over the roller while exhaling.
