Thread the Needle is a floor-based stretch that rotates the thoracic spine and opens the upper back and shoulder by sliding one arm underneath the body from a hands-and-knees position. It relieves tension built up from sitting, overhead work, or pressing movements and improves thoracic mobility with no equipment required.

How to do the Thread the Needle Pose

  1. 1Start on all fours with your hands directly under your shoulders and your knees under your hips, spine in a neutral position.
  2. 2Inhale to prepare, then on the exhale slide your right arm along the floor underneath your left arm, palm facing up.
  3. 3Continue threading the arm through until your right shoulder and right side of your head rest on the floor.
  4. 4Allow your right shoulder to sink toward the ground while your left arm remains extended in front of you for support.
  5. 5Keep your hips level and stacked over your knees — do not let them shift to one side or rotate along with your upper body.
  6. 6Hold the stretch for 20–45 seconds, breathing steadily and allowing the thoracic spine to rotate further with each exhale.
  7. 7To release, press through your left hand and slowly return your right arm back to the starting position.
  8. 8Reset to the all-fours position, then repeat on the opposite side by threading your left arm under your right arm.

Form tips

  • Let gravity do the work — once your shoulder is on the floor, relax the muscles of the upper back rather than actively pulling yourself deeper into the rotation.
  • Keep your hips directly over your knees throughout the hold; if they drift sideways you shift the stretch away from the thoracic spine and into the lumbar region.
  • Use the supporting arm to control depth — pressing the fingertips lightly into the floor allows you to regulate how far you rotate.
  • Breathe into the upper back on each inhale and allow the ribs to expand; use the exhale to soften and sink a little deeper without forcing.
  • If your shoulder does not reach the floor comfortably, place a folded towel or small block under it to avoid straining the neck.

Common mistakes

  • Letting the hips rotate or lift — this transfers the stretch from the thoracic spine to the lower back and hip, which reduces the intended effect and can cause discomfort.
  • Forcing the head down hard against the floor rather than letting it rest naturally, which compresses the cervical spine and creates unnecessary neck strain.
  • Holding the breath during the stretch, which keeps the surrounding muscles tense and limits how far the thoracic spine can rotate.
  • Threading the arm too quickly without settling into position — moving fast through the transition reduces time in the stretched range and increases the risk of catching the shoulder awkwardly.
  • Skipping the opposite side or spending significantly less time on the tighter side, which reinforces rather than corrects asymmetrical thoracic mobility.

Frequently asked questions

What does Thread the Needle Pose stretch?

The movement primarily stretches the upper back and the muscles around the shoulder blade, and it creates a rotational opening through the thoracic spine. The front of the shoulder and the muscles along the side of the neck also receive a gentle stretch depending on how far you rotate.

How long should you hold Thread the Needle?

A hold of 20–45 seconds per side is enough to allow the thoracic musculature to release. You can repeat 2–3 times per side if you are working through significant tightness, resting briefly between rounds.

Can Thread the Needle help with upper back pain?

It is commonly used to relieve the stiffness and aching that comes from prolonged sitting or repetitive overhead activity, both of which compress and reduce movement in the thoracic spine. If your pain is acute, sharp, or radiates into the arm, consult a healthcare provider before using this stretch.

When is the best time to do Thread the Needle?

It works well as part of a warm-up to prepare the thoracic spine for overhead or pressing movements, or as a cool-down stretch after upper body training. It is also effective as a standalone mobility drill first thing in the morning or after a long period of sitting.

Is Thread the Needle safe for people with shoulder injuries?

The stretch places the shoulder in an internally rotated position under mild load from body weight, which may be uncomfortable if you have an active rotator cuff issue or shoulder impingement. If you feel any pinching or sharp pain in the shoulder joint rather than a broad stretching sensation in the upper back, stop and consult a medical professional.
