🔄 Execution

The Movement

🟰 Starting Position

What's happening: Establishing stable quadruped base

1. Hands under shoulders, knees under hips
2. Spine neutral, core engaged
3. Weight evenly distributed
4. Breathing: Normal, relaxed

Feel: Stable, balanced, ready to move

🧵 Threading Phase

What's happening: Reaching one arm under body

1. Lift right hand off ground
2. "Thread" it under your left arm and body
3. Reach as far as comfortable to the left
4. Let shoulder and head follow naturally
5. Breathing: Exhale as you thread

Tempo: 2-3 seconds to thread completely

Feel: Beginning of rotation in thoracic spine

⏸️ Resting Phase

What's happening: Shoulder and head rest on ground

1. Right shoulder comes to rest on ground
2. Right ear/temple rests on ground (or hovers)
3. Right arm extended under body to left
4. Left hand still planted, supporting
5. Breathing: Deep breaths, allow gravity to work

Hold: 20-30 seconds or 5-8 deep breaths

Feel: Deep stretch in right shoulder, thoracic rotation, possible lat stretch

Key: Relax into it, don't force

⬆️ Reaching Phase (Optional)

What's happening: Opening rotation with reaching arm

1. From resting position, lift threaded arm toward ceiling
2. Rotate thoracic spine to open chest
3. Gaze follows hand upward
4. Other arm stays planted for support
5. Breathing: Inhale as you reach and open

Hold: 5-10 seconds

Feel: Maximum thoracic rotation, chest opening

Note: This is the "reverse" or "open" phase

🔄 Switch Sides

What's happening: Returning to start and switching

1. Slowly unthread arm back to starting position
2. Return to neutral quadruped
3. Repeat on opposite side (left arm threads)
4. Breathing: Exhale to return

Key Cues

Primary Cues

• "Reach your arm under like threading a needle" — name of the exercise
• "Let gravity do the work, don't force it" — passive stretch
• "Rotate from your mid-back, not your hips" — true thoracic rotation
• "Supporting arm stays strong" — stability essential

Tempo Guide

Goal	Tempo	Hold Time
Mobility	Slow entry (3s)	20-30s hold
Warm-up	Moderate entry (2s)	10-15s hold
Deep stretch	Very slow (4s)	30-60s hold

💪 Muscles Worked

Activation Overview

Primary Muscles Stretched

Muscle	Action	Activation
Thoracic Spine	Rotation — stretched on threading side	████████░░ 85%
Shoulder/Lat	Stretched as arm threads under	███████░░░ 75%
Upper Traps	Stretched along threading side	██████░░░░ 65%

Supporting Muscles

Muscle	Action	Activation
Supporting shoulder	Stabilizes body weight	██████░░░░ 60%
Core	Prevents excessive lumbar rotation	█████░░░░░ 55%

Stabilizers

Muscle	Role
Scapular stabilizers	Control shoulder blade position
Core stabilizers	Maintain neutral spine alignment

Thoracic Mobility Benefits

This stretch specifically targets thoracic rotation — one of the most limited movements in people who sit a lot. Improving thoracic rotation reduces compensatory stress on the neck and lower back.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Rotating from hips/pelvis	Pelvis rotates, not thoracic	Not addressing thoracic mobility	Keep hips square, rotate from mid-back only
Forcing the stretch	Pushing too deep too fast	Risk of strain	Let gravity work, breathe into it
Supporting arm collapses	Loss of stability	Can't relax into stretch	Keep supporting arm strong
Holding breath	Tension prevents relaxation	Limits stretch effectiveness	Breathe deeply and continuously
Neck cranking	Looking up excessively	Neck strain	Gentle head position, neutral cervical

Most Common Error

Rotating from the hips instead of the thoracic spine — your pelvis should stay square to the ground. The rotation should come from your mid-back (thoracic spine), not from twisting your hips.

Self-Check Checklist

• Hips stay square to ground (not rotating)
• Supporting arm stays strong and stable
• Breathing is deep and continuous
• Rotation comes from thoracic spine
• Neck is relaxed, not cranked

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder injury/pain	Stress on threading shoulder	Reduce depth, shorter hold
Wrist pain	Weight on supporting hand	Use fist or forearm
Knee pain	Pressure on knees	Extra padding or seated version
Severe thoracic stiffness	Limited ROM	Start with gentle, short holds

Stop Immediately If

• Sharp pain in shoulder or spine
• Pinching sensation in shoulder
• Dizziness from rotation
• Numbness or tingling in arm

Safe Practice Guidelines

Guideline	Rationale
Let gravity work	Don't force the stretch
Breathe continuously	Allows muscles to relax
Both sides equal	Even if one is tighter
Gradual progression	Don't rush depth

Normal vs. Concerning Sensations

Normal	Concerning
Stretch in shoulder/upper back	Sharp pain in shoulder
Mild tension along side	Pinching in shoulder joint
Pleasant release sensation	Numbness or tingling
Feeling of rotation/opening	Clicking with pain

🦴 Joints Involved

Joint	Action	ROM Required	Mobility Demand
Thoracic Spine	Rotation	30-40° rotation	🔴 Primary
Shoulder	Internal rotation, adduction	Moderate	🟡 Moderate
Wrist	Weight bearing (supporting side)	Neutral extension	🟢 Low

Thoracic Rotation Importance

Benefit	Explanation
Reduces neck strain	Less compensatory cervical rotation needed
Improves shoulder function	Thoracic mobility enables better shoulder mechanics
Reduces low back stress	Less compensatory lumbar rotation
Enhances sports performance	Rotational power in throwing, swinging, etc.

Joint Health Note

Thoracic rotation is one of the FIRST things we lose with desk work and aging. Thread the Needle is an excellent way to maintain or restore this critical movement pattern.

❓ Common Questions

How long should I hold the stretch?

For warm-up: 10-15 seconds. For mobility work: 20-30 seconds. For deep stretching: 30-60 seconds. The key is breathing deeply throughout the hold — each breath allows you to relax deeper.

Should I add the "reach up" phase or just thread?

Either is fine! Just threading and holding is a passive stretch (great for deep stretching). Adding the reach-up phase makes it more active and explores more range (better for warm-up/mobility). Both are beneficial.

I can barely rotate — is that normal?

Very common, especially if you sit a lot. Start where you are, don't force it. Consistent daily practice will gradually improve your rotation over weeks. Some people gain noticeable mobility within days.

My wrist hurts on the supporting hand — what can I do?

Try: (1) Making a fist instead of flat hand, (2) Going onto your forearm, (3) Using a wedge or towel under heel of hand, (4) Trying the seated or standing version instead.

One side is way tighter than the other — should I do more on that side?

Do equal reps on both sides, but you can hold the tighter side a bit longer (like 30s vs 20s). Asymmetry is very common. The tighter side will catch up with consistent practice.

For Mo

When to recommend this exercise:

• User has desk job or sits frequently
• User mentions upper back tightness or stiffness
• User has limited thoracic rotation
• User is warming up for upper body training
• User has shoulder mobility restrictions

Who should NOT do this exercise:

• Acute shoulder injury → Wait for clearance
• Severe wrist pain → Use modified version (seated/standing)
• Recent thoracic spine injury → Consult healthcare provider

Key coaching cues to emphasize:

1. "Reach your arm under like threading a needle"
2. "Keep your hips square — rotate from your mid-back only"
3. "Let gravity do the work, breathe deeply"
4. "Supporting arm stays strong and stable"

Common issues to watch for in user feedback:

• "I don't feel much" → Likely rotating from hips, cue thoracic-only rotation
• "My shoulder hurts" → Reduce depth, may have impingement
• "My wrist hurts" → Suggest fist, forearm, or seated version
• "One side way tighter" → Normal, continue equal practice

Programming guidance:

• Pair with: Cat-Cow, Thoracic Rotation
• Timing: Warm-up, desk breaks, or mobility sessions
• Typical frequency: Daily, multiple times ideal
• Volume: 3-6 reps per side, 20-30s holds

Progression signals:

• Ready to progress when: Can hold comfortably for 30s with good depth
• Add: Reach-up phase, longer holds, or dynamic flow
• Regress if: Shoulder/wrist pain, or unable to maintain stable position

Integration with other exercises:

• Excellent before: Pressing, pulling, rotational sports
• Pair with: Shoulder CARs, upper body mobility
• Complements: Strength training by maintaining thoracic mobility
