🎯 Setup

Starting Position

1. Seat height: Adjust so handles align with mid-to-lower chest (nipple line)
2. Back position: Sit upright, full back contact with pad, natural arch in lower back
3. Foot placement: Feet flat on floor, knees at 90°, stable base
4. Grip: Grasp handles (neutral or pronated depending on machine), wrists neutral
5. Shoulder position: Retract and depress shoulder blades — "scapulae in back pockets"

Equipment Setup

Equipment	Setting	Notes
Seat height	Handles at nipple/lower chest level	Too high = shoulder stress, too low = less chest activation
Back pad	Full contact, slight arch	Maintain throughout the movement
Foot position	Flat on floor or foot plate	Stable base, don't lift heels
Handle position	Most machines have adjustable start position	Start with hands roughly aligned with chest

Setup Cue

"Sit tall, chest proud, shoulder blades pinched like you're holding a pencil between them"

🔄 Execution

The Movement

🔝 Starting Position

What's happening: Loaded position with chest stretched

1. Sit with back against pad, feet planted
2. Shoulder blades retracted and depressed
3. Hands gripping handles at chest level
4. Elbows at approximately 45-75° angle from torso
5. Feel stretch across chest

Feel: Chest stretched, ready to press

➡️ Pressing

What's happening: Driving handles forward to full extension

1. Take a breath and brace core
2. Drive handles forward by pressing through the chest
3. Think "push the handles away from your chest"
4. Elbows track in natural path (typically 45-75° angle)
5. Press until arms are fully extended (but not hyperextended)

Tempo: 1-2 seconds (controlled, powerful)

Feel: Chest, front delts, and triceps working together

⏸️ Lockout

What's happening: Full arm extension

1. Arms fully extended but not hyperextended (slight bend in elbows is OK)
2. Handles pressed forward as far as the machine allows
3. Maintain shoulder blade retraction — don't let shoulders roll forward
4. Squeeze chest at the top for 1 second

Common error here: Allowing shoulders to protract (roll forward) and losing tightness

⬅️ Lowering

What's happening: Controlled return to starting position

1. Control the weight back — resist the load
2. Don't let the weight stack crash or bounce
3. Elbows track back in same path
4. Return to full stretch position at chest level
5. Brief pause, reset breath

Tempo: 2-3 seconds (slower than concentric)

Feel: Chest stretching, maintaining tension throughout

Key Cues

Primary Cues

• "Press the handles through the wall" — encourages powerful drive
• "Shoulder blades stay glued to the pad" — prevents shoulder rounding
• "Push yourself into the back pad" — maintains tension and position

Tempo Guide

Goal	Tempo	Example
Strength	2-0-1-0	2s down, no pause, 1s up, no pause
Hypertrophy	3-1-2-0	3s down, 1s pause, 2s up, no pause
Power	2-1-X-0	2s down, 1s pause, explosive up

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Pectoralis Major	Horizontal adduction — pressing arms forward and together	████████░░ 85%

Secondary Muscles

Muscle	Action	Activation
Triceps	Elbow extension — straightening the arms	███████░░░ 70%
Anterior Deltoid	Shoulder flexion — assists in forward press	██████░░░░ 60%

Stabilizers

Muscle	Role
Rotator Cuff	Stabilize shoulder joint under load
Core	Maintain upright posture, prevent rotation

Muscle Emphasis

To emphasize chest: Wider grip if available, retract scapulae hard, slower eccentric, focus on chest squeeze at lockout To emphasize triceps: Narrower grip if available, focus on elbow extension, full lockout

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Shoulders rolling forward	Shoulder blades protract at top of press	Loses chest tension, shoulder injury risk	"Keep shoulder blades pinned to the pad"
Bouncing the weight	Weight stack crashes and bounces	Less muscle work, joint stress	Control the eccentric, pause at bottom
Partial ROM	Not pressing to full extension or full stretch	Reduced effectiveness	Full ROM on every rep
Seat too high	Handles above chest level	Excessive shoulder stress, less chest activation	Adjust seat so handles align with nipple line
Arching excessively	Lower back lifts off pad	Shoulder impingement risk, loss of stability	Natural arch only, keep back against pad

Most Common Error

Losing shoulder retraction at lockout — as you press forward, it's common for shoulders to roll forward and scapulae to protract. This shifts tension off the chest and onto the front delts. Actively "keep shoulder blades back" throughout the entire rep.

Self-Check Checklist

• Seat height correct (handles at chest level)
• Shoulder blades retracted and stay retracted
• Full ROM — full extension and full stretch
• Controlled lowering, no bouncing
• Feeling it in chest, not just shoulders or triceps

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder impingement	Pain during pressing motion	Adjust seat height, reduce ROM, try neutral grip
Previous pec tear	Re-injury risk	Start very light, gradual progression
Elbow pain	Strain under load	Check grip, avoid hyperextension at lockout
Lower back issues	Excessive arch can aggravate	Maintain neutral spine, feet flat

Stop Immediately If

• Sharp pain in shoulder, chest, or elbow (not muscle burn)
• Clicking or popping with pain
• Feeling of shoulder instability
• Weight feels uncontrollable

Form Safety Guidelines

Area	Risk	Prevention
Shoulders	Impingement from improper seat height	Handles should align with mid-to-lower chest
Lower back	Hyperextension	Maintain contact with back pad, natural arch only
Elbows	Hyperextension at lockout	Full extension but not forced/hyperextended
Wrists	Strain from poor grip	Neutral wrist position, grip in palm not fingers

Advantages for Safety

Hammer Strength machines are inherently safer than free weights:

1. Can't get pinned — handles can be released safely
2. No spotter needed — safe to train alone
3. Fixed path reduces injury risk — less technical skill required
4. Independent arms — can bail out one arm if needed
5. Easy to adjust load — add/remove plates quickly

Training Alone

This is one of the safest pressing exercises to perform alone. However, always start with light weight to learn the movement pattern and never ego lift on machines.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Shoulder	Horizontal adduction, flexion	Full horizontal extension to flexion	🟡 Moderate
Elbow	Flexion/Extension	~90-180°	🟡 Moderate
Wrist	Neutral stability	Minimal movement	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Shoulder	Horizontal extension	Can bring handles to chest without pain	Reduce ROM, adjust seat
Shoulder	Horizontal adduction	Can press forward fully	Should be adequate for most
Thoracic	Neutral to slight extension	Can sit upright with natural arch	Thoracic mobility work, chest stretches

Joint Health Note

Proper seat height is critical for joint health. If handles are too high, you risk shoulder impingement. If too low, you lose chest activation. The sweet spot is handles aligning with your nipple line (mid-to-lower chest).

❓ Common Questions

How is this different from a regular machine chest press?

Hammer Strength machines are plate-loaded with independent arms (each arm moves separately), while most "regular" chest press machines are selectorized (pin-loaded) with linked arms (both arms move together). Independent arms allow you to work each side equally, identify imbalances, and have a more natural movement path similar to dumbbells.

Should I use neutral grip or pronated grip?

Use neutral grip (palms facing each other) if your machine offers it — it's more shoulder-friendly for most people. Pronated grip (palms down) is more similar to barbell bench press. Try both and use whichever feels better and gives you a better chest contraction.

Can I use this instead of barbell bench press?

Yes, especially if you train alone, have shoulder issues, or prefer the safety of machines. However, barbell bench press requires more stabilization and is generally considered superior for overall strength development. Ideally, use both — barbell for primary strength work, Hammer Strength for additional volume or when training alone.

Should I do single-arm or both arms together?

Both arms together is standard and more efficient for most training. Single-arm is excellent for: 1) Identifying and fixing strength imbalances, 2) Adding core anti-rotation work, 3) Advanced training variations. Start with bilateral (both arms) and add single-arm work as needed.

Where should the handles be relative to my chest?

At the bottom position (fully stretched), handles should be roughly aligned with your mid-to-lower chest (nipple line). If they're at your neck/upper chest, the seat is too high. If they're at your lower sternum/ribcage, the seat is too low.

Do I need to fully extend my arms?

Yes, press to full arm extension (but not hyperextension where you're forcing the elbows past straight). Full ROM is important for muscle development. However, maintain shoulder blade retraction — don't let your shoulders roll forward at lockout.

For Mo

When to recommend this exercise:

• User trains alone and wants a safe heavy pressing option
• User has shoulder issues with barbell bench (fixed path)
• User wants to identify/address strength imbalances (independent arms)
• User is beginner-to-intermediate building pressing strength
• User's gym has Hammer Strength equipment

Who should NOT do this exercise:

• Acute shoulder injury → Suggest rest, then rehab exercises
• No Hammer Strength access → Suggest barbell/dumbbell bench or selectorized machine
• User needs maximum stabilization development → Suggest barbell or dumbbell variations
• Complete beginner who needs fixed path → Suggest selectorized machine press first

Key coaching cues to emphasize:

1. "Shoulder blades stay pinned to the pad throughout"
2. "Press the handles through the wall"
3. "Push yourself into the back pad"

Common issues to watch for in user feedback:

• "My shoulders hurt" → Check seat height (should be mid-chest level), ensure shoulder blade retraction
• "I don't feel my chest" → Focus on chest squeeze, slower eccentric, ensure full ROM
• "One arm is weaker" → This is normal and why this machine is great — continue bilateral work or add single-arm sets
• "I feel it in my lower back" → Excessive arch, maintain back contact with pad, feet flat

Programming guidance:

• Pair with: Horizontal pulling (rows), vertical pressing, chest isolation
• Avoid same day as: Can pair with any push work
• Typical frequency: 2x per week for intermediates
• Volume: 3-4 sets of 8-12 reps for hypertrophy

Progression signals:

• Ready to progress when: Complete all sets/reps with 1-2 RIR and good form
• Add weight: 5-10 lbs per side when current weight feels manageable
• Regress if: Form breaking down, shoulder pain, unable to complete prescribed reps for 2+ sessions

Exercise pairing suggestions:

• After: Can be primary pressing movement, or after barbell bench for additional volume
• Before: Chest isolation (flyes, cable work), tricep work
• Superset with: Rows (push/pull), band pull-aparts (shoulder health)

Advantages over other pressing exercises:

• Safer than barbell bench (no spotter needed)
• More stable than dumbbells (easier to load heavy)
• Independent arms (unlike most selectorized machines)
• Natural pressing path (unlike Smith machine)
