🎯 Setup

Getting Into Position

1. Sit on bench with dumbbells resting on thighs
2. Lie back while using thighs to kick dumbbells up to chest level
3. Position dumbbells at sides of chest, elbows bent ~90°
4. Retract shoulder blades: Squeeze together and down
5. Feet placement: Flat on floor, stable base
6. Press up to starting position with arms extended

Equipment Setup

Equipment	Setting	Notes
Bench	Flat, stable	Ensure no wobble
Dumbbells	Appropriate weight	Start lighter than you think
Floor space	Clear around bench	Safe dumbbell drop zone

Setup Cue

"Kick-up, position, retract, then press" — master the setup before going heavy

🔄 Execution

The Movement

🔝 Starting Position

What's happening: Dumbbells locked out overhead

1. Arms fully extended, dumbbells over chest
2. Palms facing feet (pronated) OR slightly turned in
3. Shoulder blades retracted and pinned
4. Slight natural arch in lower back
5. Core braced

Feel: Chest engaged, shoulders stable

⬇️ Lowering

What's happening: Controlled descent with stretch

1. Lower dumbbells in an arc to sides of chest
2. Elbows at 45-75° angle (not 90°)
3. Keep dumbbells in line with mid-chest
4. Go deep — dumbbells can go lower than a barbell would

Tempo: 2-3 seconds

Feel: Deep stretch across chest, loading in pecs

⏸️ Bottom Position

What's happening: Maximum stretch, reversal point

1. Dumbbells at or slightly below chest level
2. Elbows below shoulder level
3. Feel deep stretch in chest
4. Brief pause or touch-and-go

Key advantage: Greater range of motion than barbell

⬆️ Pressing

What's happening: Driving dumbbells up and together

1. Press up in an arc — dumbbells move up AND slightly together
2. Think "draw a rainbow" with the path
3. Push through chest, not just arms
4. Keep shoulder blades retracted throughout

Tempo: 1-2 seconds

Feel: Chest contracting, triceps finishing lockout

Key Cues

Primary Cues

• "Draw a rainbow" — arc path, not straight up
• "Squeeze at the top" — bring dumbbells together, contract chest
• "Elbows at 45" — protect shoulders, optimize chest activation

Grip Options

Grip	Description	Emphasis
Pronated	Palms facing feet	Standard, most chest
Neutral	Palms facing each other	Shoulder-friendly
Rotating	Rotate from neutral to pronated during press	Natural path, more supination

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Pectoralis Major	Horizontal adduction — bringing arms together	████████░░ 85%

Secondary Muscles

Muscle	Action	Activation
Triceps	Elbow extension — straightening arms	██████░░░░ 60%
Anterior Deltoid	Shoulder flexion — assists press	█████░░░░░ 55%

Stabilizers

Muscle	Role
Rotator Cuff	Stabilize shoulder — higher demand than barbell (free weights)
Biceps	Control dumbbells during descent
Core	Maintain body position

Dumbbell Advantage

Greater ROM: Dumbbells can go lower than a barbell, stretching the chest more Better contraction: Can bring dumbbells together at top for peak contraction Stabilizer work: Each arm works independently, building balanced strength

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Going too heavy	Can't control dumbbells	Injury risk, poor form	Start lighter, nail form first
Straight up path	Press straight up, not arc	Less chest activation	"Draw a rainbow"
Flaring elbows	Elbows at 90°	Shoulder impingement	Tuck to 45-75°
Bouncing at bottom	No pause, momentum-driven	Less muscle work	Control the stretch
Dumbbells drifting apart	DBs move outward at top	Lose tension	Squeeze them together

Most Common Error

Ego lifting — because each dumbbell is half the weight of a barbell, people often go too heavy. Start with 60-70% of what you'd expect and focus on control and ROM.

Self-Check Checklist

• Controlled descent, no bouncing
• Full range of motion (deep stretch at bottom)
• Dumbbells come together at top
• Shoulder blades stay retracted
• Elbows at ~45°, not 90°

Best for	Advanced lifters, variety

Movement Variations

Variation	Change	Why
Alternating DB Press	Press one at a time	Core anti-rotation, fix imbalances
Single-Arm DB Press	One dumbbell only	Heavy core work, unilateral strength
Tempo DB Press	4s lowering	More time under tension
Pause DB Press	2s pause at bottom	Build starting strength

Equipment Variations

Equipment	Exercise Name	Key Difference
Barbell	Bench Press	More load, fixed path
Bodyweight	Push-Up	No equipment needed
Cables	Cable Chest Press	Constant tension
Floor	Dumbbell Floor Press	Limited ROM, tricep emphasis

Hypertrophy	3-4	8-12	90s-2 min	1-3
Endurance	2-3	15-20+	60-90s	2-4

Workout Placement

Program Type	Placement	Rationale
Chest day	After barbell work OR primary	Depends on priority
Push day	After barbell bench	More ROM, addresses imbalances

Frequency

Training Level	Frequency	Volume Per Session
Beginner	2-3x/week	3 sets
Intermediate	2x/week	3-4 sets
Advanced	2x/week	4 sets

Weight Selection

Most people can dumbbell press about 70-80% of their barbell bench (per dumbbell). If you bench 200 lbs, expect to use 70-80 lb dumbbells for similar reps.

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder instability	Dumbbells harder to control	Use lighter weight, machine press
Rotator cuff issues	High stabilizer demand	Use neutral grip, limit ROM
Inexperience	Dumbbell control	Master with light weight first

Stop Immediately If

• Sharp shoulder pain
• Can't control one or both dumbbells
• Clicking with pain
• Numbness in arms

Safe Dumbbell Drop

How to safely bail:

1. Lower dumbbells to chest
2. Roll them off to the sides onto floor
3. Don't try to rack or throw them

Spotting

Unlike barbell, spotting dumbbells means pushing at the wrists/forearms, not the elbows. Or simply be ready to help them lower to sides.

---

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Shoulder	Horizontal adduction, flexion	Full — can go deeper than barbell	🟡 Moderate
Elbow	Flexion/Extension	~90-180°	🟡 Moderate

Mobility Requirements

Joint	Minimum ROM	If Limited
Shoulder	Full horizontal extension	Limit depth, use floor press
Thoracic	Adequate extension	Foam roll, reduce arch

Joint Advantage

Dumbbells allow your wrists, elbows, and shoulders to find their natural path, reducing joint stress compared to a fixed barbell position.

❓ Common Questions

What weight should I start with?

If you know your barbell bench, start with dumbbells at about 35-40% of that weight each. So if you bench 150 lbs, try 25-30 lb dumbbells to start. If you're completely new, start with 10-15 lb dumbbells to learn the movement.

Is dumbbell or barbell bench better?

Neither is universally better — they're complementary. Barbell allows more weight. Dumbbells offer more ROM, address imbalances, and may be more shoulder-friendly. Many programs use both.

Should I touch the dumbbells together at the top?

They don't need to touch, but bringing them close together (nearly touching) creates a better peak contraction in the chest. Don't clang them together — controlled squeeze.

How do I safely get heavy dumbbells into position?

The "kick-up": Sit on bench with dumbbells on thighs. Lie back while using thighs to kick/push dumbbells up to chest level. Practice with lighter weights first. For very heavy weights, consider having a spotter hand them to you.

For Mo

When to recommend this exercise:

• User wants to build chest with dumbbells
• User has shoulder discomfort with barbell pressing
• User wants to address left/right imbalances
• User is a beginner learning pressing patterns
• User only has access to dumbbells

Who should NOT do this exercise:

• Extremely unstable shoulder → Suggest machine press
• Can't safely handle dumbbells into position → Suggest push-ups or machine
• No bench → Suggest floor press or push-ups

Key coaching cues to emphasize:

1. "Draw a rainbow" — arc path, not straight up
2. "Squeeze at the top" — peak chest contraction
3. "Control the stretch" — don't bounce at bottom

Common issues to watch for in user feedback:

• "I can't get into position" → Teach kick-up, or use lighter weight
• "My shoulders hurt" → Try neutral grip, check elbow flare
• "I don't feel my chest" → Slow down, focus on stretch and squeeze

Programming guidance:

• Pair with: Rows, flyes, tricep work
• Common approach: Use after barbell bench for extra volume
• Alternative approach: Use as primary press if shoulder issues
• Typical frequency: 1-2x per week

Progression signals:

• Ready to progress when: Can complete all reps with full ROM
• Add weight: 5 lbs per dumbbell when ready
• Consider barbell bench if: Wants to lift heavier, has good form
