🔄 Execution

The Movement

🟰 Starting Position

What's happening: Establishing proper arm and body position

1. Stand in doorway, facing forward
2. Right arm bent 90°, forearm on door frame
3. Elbow at shoulder height
4. Feet in staggered stance for stability
5. Breathing: Normal, relaxed

Feel: Arm positioned, ready to stretch

⬆️ Entering the Stretch

What's happening: Creating the stretch through forward movement

1. Slowly step forward with front foot, OR
2. Gently lean/rotate torso forward and through doorway
3. Keep forearm planted on frame
4. Chest moves forward through the plane of the doorway
5. Breathing: Exhale as you move into stretch

Tempo: 2-3 seconds to enter

Feel: Stretch beginning across chest and front shoulder

⏸️ Hold Position

What's happening: Static hold for tissue lengthening

1. Hold position where you feel moderate stretch
2. Keep shoulder down and back (don't shrug)
3. Chest up, sternum lifted
4. Breathe deeply and continuously
5. Breathing: 5-10 deep breaths

Hold: 30-60 seconds

Feel: Sustained stretch across pec, front shoulder

Common sensation: May feel stretch into bicep or front shoulder

🔄 Angle Adjustments

What's happening: Targeting different pec muscle fibers

High position (arm higher):

• Raise arm overhead, elbow above shoulder
• Targets lower pec fibers

Mid position (standard):

• Elbow at shoulder height
• Targets mid pec fibers

Low position (arm lower):

• Lower arm, elbow below shoulder
• Targets upper pec and clavicular fibers

Try all three positions for complete chest stretch

🔄 Switch Sides

What's happening: Repeating on opposite side

1. Slowly release stretch, step back
2. Switch arms (left arm on frame)
3. Repeat entire sequence
4. Breathing: Reset breathing

Key Cues

Primary Cues

• "Step through the doorway, let your chest open" — the movement
• "Keep shoulder down and back, don't shrug" — proper shoulder position
• "Chest up, proud posture" — enhances stretch
• "Move slowly, breathe deeply" — safety and effectiveness

💪 Muscles Worked

Activation Overview

Primary Muscles Stretched

Muscle	Action	Activation
Pectoralis Major	Stretched as shoulder extends/externally rotates	█████████░ 90%
Anterior Deltoid	Stretched with shoulder extension	████████░░ 80%
Pectoralis Minor	Stretched with scapular retraction	███████░░░ 75%

Secondary Muscles Stretched

Muscle	Action	Activation
Biceps	Stretched with elbow position	██████░░░░ 60%
Front shoulder capsule	Stretched with external rotation	██████░░░░ 55%

Stabilizers

Muscle	Role
Scapular retractors	Pull shoulder blade back
Core	Maintains upright posture

Why Pecs Get Tight

Modern life creates chest tightness: desk work, driving, phone use, and bench pressing all shorten the pecs. This creates rounded shoulders and forward head posture. This stretch reverses that pattern.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Shrugging shoulder up	Shoulder elevates toward ear	Reduces stretch, strains neck	"Shoulder down and back" cue
Arching lower back	Lumbar hyperextension	Fake chest opening via back arch	Ribs down, core engaged
Arm too high or too low	Wrong muscle fibers targeted	Incomplete pec stretch	Start at shoulder height
Forcing too deep	Aggressive stretch	Risk of strain	Gradual progression only
Holding breath	Muscle tension	Prevents tissue relaxation	Breathe deeply and continuously

Most Common Error

Shrugging the shoulder up — your shoulder should stay DOWN and BACK throughout. If it rises toward your ear, you're compensating and missing the stretch.

Self-Check Checklist

• Shoulder stays down and back (not shrugged)
• Chest up, sternum lifted
• Core engaged (ribs not flaring)
• Feeling stretch in chest, not shoulder joint pain
• Breathing deeply and continuously

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder impingement	Pain with stretch	Reduce depth, lower arm position
Shoulder instability/dislocation history	Risk of subluxation	Very gentle, avoid end-range
Biceps tendinitis	Aggravation of tendon	Reduce depth, focus on pec only
Recent shoulder surgery	Disruption of healing	Wait for clearance

Stop Immediately If

• Sharp pain in shoulder joint
• Feeling of shoulder "slipping" or instability
• Numbness or tingling down arm
• Pain radiating into neck

Safe Practice Guidelines

Guideline	Rationale
Start gentle, progress gradually	Tissues need time to adapt
Never bounce or force	Static stretch should be smooth
Keep shoulder "packed" (down and back)	Protects shoulder joint
Breathe continuously	Allows muscle relaxation

Normal vs. Concerning Sensations

Normal	Concerning
Stretch across chest muscle	Sharp pain in shoulder joint
Mild pulling in front shoulder	Feeling of joint instability
Pleasant release sensation	Numbness or tingling in arm
Stretch into bicep area	Severe pain anywhere

🦴 Joints Involved

Joint	Action	ROM Required	Mobility Demand
Shoulder (Glenohumeral)	Horizontal abduction, external rotation	Moderate	🔴 Primary
Sternoclavicular	Slight retraction	Minimal	🟡 Moderate
Acromioclavicular	Scapular movement	Minimal	🟢 Low

Postural Benefits

Benefit	Explanation
Reduced rounded shoulders	Lengthens tight pecs that pull shoulders forward
Improved head position	Less forward head posture
Better breathing	Open chest allows fuller breath
Enhanced shoulder function	Balanced muscle length around shoulder

Why This Matters for Athletes

Activity	Benefit
Bench pressers	Prevents excessive tightness from pressing
Overhead athletes	Maintains shoulder balance
Desk workers	Reverses seated posture patterns
Swimmers	Balances internal rotation dominance

Joint Health Note

Chronically tight pecs contribute to shoulder impingement and rotator cuff issues. Regular pec stretching is preventive medicine for shoulder health, especially if you bench press or sit frequently.

❓ Common Questions

Should I stretch my pecs before or after bench pressing?

AFTER is better. Pre-workout, do dynamic mobility instead (arm circles, band pull-aparts). Post-workout, when muscles are warm, is ideal for static stretching. Aggressive static stretching pre-workout may temporarily reduce strength.

How do I know which arm height to use?

Try all three! Start at shoulder height (mid pecs), then try higher (targets lower pecs) and lower (upper pecs). Where you feel the most tightness is where you likely need the most work.

I feel this in my shoulder joint, not my chest — what's wrong?

This suggests possible shoulder impingement or your arm is too far back. Try: (1) Lower your arm position, (2) Don't step as far forward, (3) Keep shoulder more "packed" (down and back), (4) If pain persists, consult a professional.

Can I do this if I have rounded shoulders?

Yes — in fact, you SHOULD! Rounded shoulders often come from tight pecs pulling shoulders forward. This stretch addresses that. Combine with strengthening exercises for upper back (rows, face pulls) for best results.

How long until I see posture improvement?

With daily practice, many people notice improved shoulder position within 2-3 weeks. Significant postural changes take 6-8 weeks of consistent stretching + strengthening of opposing muscles.

For Mo

When to recommend this exercise:

• User has desk job or sits frequently
• User benches presses regularly
• User has rounded shoulders or forward head posture
• User mentions chest tightness
• User is cooling down after chest/push workout

Who should NOT do this exercise:

• Acute shoulder injury → Wait for clearance
• Shoulder instability/frequent dislocations → Very gentle or avoid
• Severe shoulder pain → Consult healthcare provider

Key coaching cues to emphasize:

1. "Shoulder stays down and back — don't shrug it up"
2. "Step through the doorway gently, chest opens"
3. "Chest up, proud posture throughout"
4. "Breathe deeply — each breath lets you relax deeper"

Common issues to watch for in user feedback:

• "I feel it in my shoulder, not chest" → Arm too far back, reduce depth
• "I don't feel much" → Try different arm heights, step further forward
• "My shoulder hurts" → Possible impingement, reduce depth or stop
• "One side way tighter" → Common, continue equal practice

Programming guidance:

• Pair with: Band Pull-Apart, rows, rear delt work
• Timing: Post-workout (when warm), or daily as mobility practice
• Typical frequency: Daily, especially for bench pressers and desk workers
• Volume: 1-3 reps per side, 30-60s holds, try all 3 arm heights

Progression signals:

• Ready to progress when: Can hold comfortably 60s at all three positions
• Add: Weighted stretch, dynamic pulsing, or longer holds
• Regress if: Shoulder pain, clicking with pain, or instability sensation

Integration with other exercises:

• Excellent after: Bench press, push-ups, any pressing
• Pair with: Upper back strengthening (rows, face pulls, pull-aparts)
• Complements: Pressing by maintaining shoulder balance and health
