The reverse sleeper stretch targets the subscapularis and anterior shoulder capsule by driving the shoulder into external rotation while lying on your side. This mobilization improves overhead and front rack positions by addressing internal rotation bias and anterior tightness.

Setup

  1. Lie on your side with the target shoulder directly underneath you. Bend the bottom arm to 90 degrees at the shoulder and elbow, forearm resting on the floor in front of you.
  2. Use your top hand to gently lift your bottom forearm upward (toward the ceiling), rotating the shoulder externally. Your elbow stays pinned to the floor.
  3. Hold at the point of a comfortable stretch. The scapula is stabilized by your body weight.
  4. After the hold, slowly lower back to the start.

Coaching Cues

What to feel:

  • A stretch in the front of the shoulder and across the chest
  • The shoulder blade pinned and stable underneath you

Common mistakes:

  • Rolling backward, which releases the scapula and reduces the stretch
  • Forcing into excessive external rotation — this should be a gentle, sustained hold
  • Placing the elbow above shoulder height, which may cause impingement

Video and animated demos coming soon.

When to do it Upper body focus, full mobility session, desk breaks, post-workout

Progressions

  1. Beginner: Minimal overpressure; focus on finding the correct position.
  2. Intermediate: Moderate overpressure with the top hand as described.
  3. Advanced: Add gentle contract-relax cycles — push the forearm down for 5 seconds, then relax into more external rotation.
