🎯 Setup

Starting Position

1. Seat height: Adjust so handles align with mid-chest (nipple line)
2. Back position: Sit with back flat against pad, shoulder blades retracted
3. Handle position: Grip handles at chest level — elbows should be at 90° or slightly below shoulders
4. Foot placement: Feet flat on floor or footrest, knees at 90°
5. Starting depth: Handles should be at or slightly behind chest level (machine dependent)

Equipment Setup

Equipment	Setting	Notes
Seat height	Handles at mid-chest	Most critical adjustment
Handle depth	Maximum comfortable stretch	Don't force excessive ROM
Footrest	Feet flat, stable base	Some machines have adjustable footrests

Setup Cue

"Chest up, shoulders back and down — press from a strong, stable position"

🔄 Execution

The Movement

⬆️ Pressing

What's happening: Pushing handles forward to full extension

1. Take a breath and brace your core
2. Press handles forward in a smooth, controlled motion
3. Keep shoulder blades retracted against the pad
4. Drive through your chest and triceps
5. Extend to full lockout (don't hyperextend elbows)

Tempo: 1-2 seconds

Feel: Chest, front delts, and triceps working together

🔝 Lockout

What's happening: Full arm extension at the end range

1. Lock elbows completely at top (without hyperextending)
2. Maintain shoulder blade retraction — don't let shoulders roll forward
3. Handles should be aligned straight out from chest
4. Pause briefly if desired for peak contraction

Common error here: Letting shoulders roll forward at lockout. Keep them pinned back.

⬇️ Lowering

What's happening: Controlled return to starting position

1. Slowly control the weight back
2. Don't just let the stack drop — resist the negative
3. Elbows should stay at 45-75° from body (not flared wide)
4. Lower until handles are at chest level or slight stretch

Tempo: 2-3 seconds (slower than concentric)

Feel: Stretch across chest, maintaining tension

⏸️ Stretch Position

What's happening: Full stretch at the bottom position

1. Handles at or slightly behind chest level
2. Feel a stretch across the chest
3. Don't bounce — maintain control
4. Keep core braced, back against pad

Key Cues

Primary Cues

• "Chest to the ceiling" — maintains posture throughout
• "Push the handles through the wall" — drive with intent
• "Shoulders stay back" — prevents rounding forward

Tempo Guide

💪 Muscles Worked

Activation Overview

Primary Movers

Muscle	Action	Activation
Pectoralis Major	Horizontal adduction — pushing handles forward	████████░░ 80%

Secondary Muscles

Muscle	Action	Activation
Triceps	Elbow extension — straightening the arms	███████░░░ 65%
Anterior Deltoid	Shoulder flexion — assists in pressing	██████░░░░ 55%

Stabilizers

Muscle	Role
Rotator Cuff	Stabilize shoulder joint during movement
Core	Maintain upright posture, prevent arch

Muscle Emphasis

To emphasize chest: Wider grip, focus on squeeze at lockout, slower eccentric To emphasize triceps: Narrower grip if available, focus on lockout, elbows tucked

---

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Shoulders rolling forward	Shoulders round at lockout	Reduces chest activation, shoulder strain	Keep shoulder blades pinned to pad
Bouncing the weight	Using momentum at bottom	Less muscle work, potential injury	Control the eccentric, pause at bottom
Partial ROM	Not extending fully or not lowering enough	Missing muscle activation	Use full range, adjust weight if needed
Feet not planted	Feet off floor or moving	Less stability, inefficient	Keep feet flat, push into floor
Head forward	Neck craning forward	Neck strain, poor posture	Head against pad, neutral neck

Most Common Error

Letting shoulders round forward at lockout — this shifts tension away from the chest. Keep those shoulder blades retracted throughout the entire movement.

Self-Check Checklist

• Seat height allows handles to align with mid-chest
• Shoulder blades stay retracted against pad
• Full range of motion (stretch to lockout)
• Feet planted firmly on floor
• Controlled tempo, no bouncing

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder impingement	Pain during press	Reduce ROM, use neutral grip
Previous pec tear	Re-injury risk	Start very light, gradual progression
Wrist pain	Strain on wrists	Adjust grip, use neutral handles
Low back issues	Arching against pad	Focus on core bracing

Stop Immediately If

• Sharp pain in shoulder or chest (not muscle burn)
• Clicking/popping with pain
• Numbness or tingling in arms
• Loss of control during movement

Machine Safety

Safety Aspect	Best Practice
Seat adjustment	Lock seat securely before starting
Weight stack	Start light to test ROM and form
Emergency stop	Know how to safely stop mid-rep
Clearance	Ensure handles have clear path

Safe Failure

How to safely fail on a machine:

1. Most machines: Simply release handles — weight stack stops safely
2. Control the negative: Even when failing, guide weight down slowly
3. Don't fight it: If you can't complete a rep, control it back to start
4. Ask for help: If stuck, signal for assistance

Advantages of Machines

Machines are inherently safer than free weights — the fixed path prevents the weight from falling on you. This makes them excellent for training to failure safely.

🦴 Joints Involved

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

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Shoulder	Horizontal extension without pain	Can bring handles to chest	Reduce depth, work mobility
Thoracic	Ability to sit upright	Can maintain upright posture	Thoracic extensions, foam rolling
Wrist	Can grip handles comfortably	No wrist pain during press	Use neutral grip if available

Joint Health Note

The fixed path of machines reduces joint stress compared to free weights, making this exercise excellent for those with minor shoulder issues. However, if the machine's path doesn't match your biomechanics, it can cause discomfort — listen to your body.

❓ Common Questions

How is this different from bench press?

The machine provides a fixed movement path, requiring less stabilization. This makes it easier to learn and safer to train to failure. However, you'll lift less weight than a barbell bench press because you're not recruiting stabilizer muscles. Machines are great for isolating the chest after heavy compound work.

Should I go all the way back on the eccentric?

Go to a comfortable stretch — you should feel tension in the chest but not pain. Don't force excessive ROM if your machine allows handles to go too far back. The stretch should be at or just behind the chest plane.

Can beginners start with this exercise?

Yes! This is one of the best exercises for beginners to learn the horizontal pressing pattern safely. The fixed path reduces the learning curve and allows you to focus on pushing hard without worrying about balance.

Should I lock out my elbows completely?

Yes, but don't hyperextend. Full lockout ensures complete ROM and tricep engagement. Just don't slam into lockout — maintain control throughout.

What if the machine doesn't fit my body?

Not all machines fit all bodies. If you can't get comfortable even after adjusting the seat, or if the path feels wrong, choose a different exercise. Free weights (dumbbells or barbell) or a different machine model might work better.

Can I build muscle with just machines?

Absolutely. Muscles respond to tension, volume, and progressive overload — all of which machines provide. While free weights offer benefits, machines are perfectly effective for muscle growth.

Key coaching cues to emphasize:

1. "Chest up, shoulders back and pinned to the pad"
2. "Push through your chest, not just your arms"
3. "Control the weight down — don't let it drop"

Common issues to watch for in user feedback:

• "I don't feel it in my chest" → Check shoulder position, ensure retraction throughout
• "My shoulders hurt" → Check seat height and ROM, may need to reduce depth
• "The machine feels awkward" → May need different machine or switch to dumbbells
• "I'm not progressing" → Add volume, slow tempo, or ensure they're training close to failure

Programming guidance:

• Pair with: Rows, vertical press, tricep/bicep work
• Avoid same day as: Too much other heavy pressing (manage fatigue)
• Typical frequency: 2-3x per week for beginners, 2x for intermediates

Progression signals:

• Ready to progress when: Can complete all sets with 1-2 RIR consistently
• Add weight: 5-10 lbs per session for beginners, weekly for intermediates
• Progress to free weights when: Comfortable with movement, want more challenge
• Regress if: Experiencing pain, form consistently breaks down
