🎯 Setup

Starting Position

1. Grip: Underhand (supinated) grip on the bar
   • Palms facing toward you
   • Hands shoulder-width apart or slightly narrower
2. Hang: Full dead hang with arms completely extended
3. Shoulders: Start with shoulders slightly elevated, prepare to depress
4. Core: Brace core to prevent swinging
5. Legs: Keep legs straight or cross ankles, minimal movement

Equipment Setup

Equipment	Setting	Notes
Bar height	High enough for full dead hang	Feet clear the ground
Grip aids	Optional chalk	Improves grip security
Assistance	Bands or machine	For building up strength

Setup Cue

"Palms toward you, shoulder-width grip, hang dead and ready"

🔄 Execution

The Movement

⬇️ Dead Hang

What's happening: Full extension, loaded stretch

1. Arms completely straight, hanging from bar
2. Biceps and lats under stretch
3. Core engaged to prevent swing
4. Breathing: Deep breath before initiating pull

Feel: Stretch in lats and biceps, grip engaged

🔥 Engagement Phase

What's happening: Scapula and lat activation

1. Depress and retract shoulder blades first
2. "Pull shoulders down and back"
3. Slight upward movement before arms bend
4. Breathing: Hold breath through pull

Key: Engage back before arms — don't just curl yourself up

⬆️ Pulling Up

What's happening: Combined lat and bicep pull

1. Pull elbows down toward your sides
2. Think "drive elbows to hip pockets"
3. Chest rises toward bar, not just chin
4. Pull until chin clears bar or chest touches bar

Tempo: 1-2 seconds (smooth and controlled)

Feel: Biceps working hard, lats contracting, back squeezing

🔝 Top Position

What's happening: Peak contraction, maximum bicep engagement

1. Chin over bar (minimum) or upper chest to bar (ideal)
2. Elbows fully flexed, pulled down and slightly back
3. Shoulder blades retracted together
4. Brief squeeze at top

Breathing: Brief exhale or continue holding

⬇️ Lowering

What's happening: Resisting gravity with control

1. Lower yourself slowly — don't drop
2. Maintain tension in lats and biceps
3. Gradually extend arms back to dead hang
4. Breathing: Inhale on the way down

Tempo: 2-3 seconds (controlled negative)

Feel: Eccentric bicep and lat engagement, full stretch at bottom

Key Cues

Primary Cues

• "Shoulders first, then arms" — initiate with scapula, not biceps
• "Pull chest to bar" — ensures full range of motion
• "Elbows to your sides" — optimal pulling mechanics

Tempo Guide

Goal	Tempo	Example
Strength	1-0-2-0	1s up, no pause, 2s down, no pause
Hypertrophy	2-1-3-0	2s up, 1s pause, 3s down, no pause
Bicep Emphasis	2-2-4-0	2s up, 2s squeeze, 4s down (max TUT)

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Latissimus Dorsi	Shoulder extension — pulling body upward	█████████░ 85%
Biceps Brachii	Elbow flexion — major pulling force with underhand grip	█████████░ 88%

Secondary Muscles

Muscle	Action	Activation
Upper Back	Scapular retraction and control	███████░░░ 70%
Brachialis	Elbow flexion — deep arm muscle	███████░░░ 72%

Stabilizers

Muscle	Role
Forearms	Grip strength and wrist stability
Core	Anti-extension, prevent swinging

Muscle Emphasis

Chin-up vs Pull-up: Chin-ups recruit significantly more biceps (88% vs 70%) due to the underhand grip placing biceps in a mechanically advantageous position. Lat activation is similar, but chin-ups allow most people to do more reps.

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
All arms, no back	Curling yourself up without scapula engagement	Misses lat development, shoulder stress	"Shoulders down and back first" cue
Partial ROM	Not going to full dead hang	Less muscle activation, cheating	Reset to dead hang every rep
Swinging/kipping	Using momentum to complete reps	Less strength gains, injury risk	Slow tempo, engage core
Head jutting forward	Reaching with chin only	Neck strain, incomplete ROM	Pull chest to bar instead
Elbows flaring out	Elbows drift away from body	Less efficient, shoulder stress	"Elbows to sides" cue

Most Common Error

Skipping the dead hang — not returning to full extension between reps cuts range of motion and reduces both strength gains and muscle development. Every rep starts from a complete dead hang.

Self-Check Checklist

• Full dead hang between every rep
• Shoulders retract before arms bend
• Chest reaches toward bar, not just chin
• No swinging or kipping
• Controlled 2-3 second lowering

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Bicep tendinitis	Stress on bicep tendon insertion	Reduce volume, use neutral grip
Shoulder impingement	Overhead pulling strain	Limit ROM, use assisted variation
Elbow strain	Repetitive flexion stress	Lower volume, longer rest periods
Golfer's elbow	Medial epicondyle stress	Switch to neutral or overhand grip

Stop Immediately If

• Sharp pain in bicep or elbow
• Popping sensation in shoulder or elbow
• Inability to fully extend arm after set
• Numbness or tingling in arms

Injury Prevention

Strategy	Implementation
Proper warm-up	Dead hangs, scapula pulls, light band curls
Volume management	Don't exceed 15-20 total reps per session initially
Full ROM	Always return to dead hang
Balanced training	Include pushing exercises

Safe Failure Protocol

1. Can't complete rep: Lower yourself in a controlled eccentric
2. Grip failing: Use lifting straps to prevent unexpected drops
3. Mid-rep failure: Control the descent, don't just fall

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Shoulder	Extension, Adduction	Full overhead ROM	🔴 High
Elbow	Flexion/Extension	0-145° flexion	🔴 High
Scapula	Depression, Retraction	Full scapular mobility	🟡 Moderate
Wrist	Neutral position	Minimal movement	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Shoulder	Full flexion overhead	Dead hang without discomfort	Shoulder mobility work, wall slides
Elbow	Full flexion and extension	Can fully straighten and bend arm	Elbow stretches, gradual ROM work
Forearm	Supination (palm up)	Can turn palm completely upward	Forearm stretches

Joint Health Note

The underhand grip places more stress on the bicep tendon and elbow compared to overhand pull-ups. If you experience elbow pain, reduce volume, ensure full extension between reps, and consider alternating with neutral-grip variations.

❓ Common Questions

Chin-ups vs pull-ups — which should I do?

Both are valuable. Chin-ups allow most people to do more reps and emphasize biceps more heavily. Pull-ups emphasize lats and upper back slightly more. Ideally, include both in your program, or alternate them in different training blocks.

Are chin-ups enough for bicep growth?

Chin-ups are excellent for biceps and should be a staple. However, for maximum bicep development, add isolation work like barbell or dumbbell curls. Chin-ups provide the heavy compound work; curls add volume in different positions.

Why can I do more chin-ups than pull-ups?

The underhand grip places your biceps in a stronger mechanical position, allowing them to contribute more force. Most people can do 1-3 more chin-ups than pull-ups. This is normal and expected.

Should I go all the way down to a dead hang?

Yes. Full dead hangs ensure complete range of motion, which is crucial for both muscle development and shoulder health. Partial reps are less effective and can develop strength imbalances.

My elbows hurt during chin-ups. What should I do?

Elbow pain often indicates overuse or poor recovery. Reduce frequency and volume, ensure you're fully extending at the bottom (not staying partially bent), and consider adding neutral-grip variations. If pain persists, consult a medical professional.

For Mo

When to recommend this exercise:

• User wants to build biceps and back together
• User has chin-up bar access
• User prefers bodyweight training or wants to progress to weighted

Who should NOT do this exercise:

• Acute bicep or elbow injury → Suggest Lat Pulldown with neutral grip
• Severe shoulder issues → Suggest Seated Cable Row
• Complete beginner unable to do negatives → Start with Inverted Row

Key coaching cues to emphasize:

1. "Shoulders down and back before pulling"
2. "Pull your chest to the bar"
3. "Full dead hang between every rep"

Common issues to watch for in user feedback:

• "Can't do one yet" → Negatives and band assistance
• "Elbow pain" → Check form, reduce volume, try neutral grip
• "Not feeling lats" → Emphasize scapula engagement first

Programming guidance:

• Pair with: Horizontal push (bench press), overhead press
• Works well with: Barbell curls (finish arm work), rows (complete back)
• Typical frequency: 2-3x per week

Progression signals:

• Ready to add weight: 10-12 strict reps with good form
• Regress if: Can't do 3 reps without swinging, elbow pain develops
