🎯 Setup

Starting Position

1. Seat height: Adjust so handles align with mid-chest (nipple line)
2. Back position: Sit fully against backrest, shoulder blades against pad
3. Handle height: Handles should be at sternum/nipple level when seated
4. Foot placement: Feet flat on floor or foot plate, stable base
5. Grip: Grasp handles with full grip, wrists neutral

Equipment Setup

Adjustment	Setting	Notes
Seat height	Handles at mid-chest	Usually 3-5 holes from bottom
Backrest	Upright 90°	Some machines allow slight recline
Handle position	Chest-level start	Handles should be even with chest at rest
Weight stack	Conservative start	Test with light weight first

Setup Cue

"Sit like you're driving — back flat against the seat, chest proud, feet planted"

🔄 Execution

The Movement

⬇️ Return Phase

What's happening: Controlled return to chest

1. From extended position, begin to bend elbows
2. Let handles move back toward chest under control
3. Keep shoulder blades pinned to backrest
4. Maintain chest up, avoid rounding shoulders forward
5. Stop when handles are at chest level or elbows at 90°

Tempo: 2-3 seconds

Feel: Stretch across chest, loading the pecs eccentrically

⏸️ Starting Position

What's happening: Handles at chest, ready to press

1. Handles level with mid-chest
2. Elbows at approximately 45-75° from body
3. Wrists straight, not bent back
4. Shoulder blades stay retracted against pad
5. Core braced, no arching away from backrest

Common error here: Letting shoulders roll forward or losing back contact with the pad

⬆️ Pressing

What's happening: Pushing handles away from chest

1. Take a breath and brace core
2. Drive handles forward and slightly together
3. Think "push the machine away from you"
4. Maintain back contact with pad throughout
5. Keep shoulders down, don't shrug up

Tempo: 1-2 seconds (controlled, powerful)

Feel: Chest, triceps, and front delts contracting forcefully

🔝 Lockout

What's happening: Full arm extension at end range

1. Press to full elbow extension (don't hyperextend)
2. Handles should be slightly converged from start
3. Shoulder blades stay back, don't protract forward
4. Squeeze chest at the top
5. Maintain tension before returning

Key Cues

Primary Cues

• "Chest to the ceiling" — keeps torso upright and pecs engaged
• "Push the machine through the wall" — ensures full extension
• "Shoulder blades glued to the pad" — prevents compensation

💪 Muscles Worked

Activation Overview

Primary Movers

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

Secondary Muscles

Muscle	Action	Activation
Triceps	Elbow extension — straightening the arms	██████░░░░ 65%
Anterior Deltoid	Shoulder flexion — assists the press	██████░░░░ 60%

Stabilizers

Muscle	Role
Rotator Cuff	Stabilize shoulder joint throughout ROM
Core	Maintain upright torso position

Muscle Emphasis

To emphasize chest: Wider grip option, focus on squeezing handles together at top, slow eccentric To emphasize triceps: Narrow grip if available, full lockout emphasis, think "push through elbows"

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Shoulders rounding forward	Upper back lifts off pad	Reduces chest activation, strains shoulders	"Shoulder blades pinned" throughout
Partial range of motion	Not returning to chest	Limits muscle stretch and growth	Full return until elbows at 90°
Bouncing the weight	Using momentum to start press	Less muscle work, joint stress	Control the return, pause at chest
Seat height wrong	Handles too high or low	Poor leverage, shoulder strain	Handles should align with mid-chest
Feet off ground	Unstable base	Power leak, balance issues	Feet flat, push into floor

Most Common Error

Losing scapular retraction — the fixed path tempts you to let shoulders round forward. Keep those shoulder blades back against the pad like you're pinching a pencil between them.

Self-Check Checklist

• Seat adjusted so handles are mid-chest level
• Back flat against pad entire time
• Shoulder blades stay retracted (pinched back)
• Full range of motion (chest to lockout)
• Feet planted firmly on floor

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder impingement	Pain during pressing	Reduce ROM, use neutral grip
Previous pec tear	Re-injury risk	Start very light, slow progression
Low back pain	Arching away from pad	Keep back flat against pad, brace core
Wrist pain	Strain with fixed grip	Adjust seat height, check handle position

Stop Immediately If

• Sharp pain in shoulder or chest (not muscle burn)
• Clicking or grinding in shoulder joint
• Numbness or tingling in arms
• Inability to control the weight smoothly

Safety Advantages

Safety Feature	Benefit
Fixed path	Can't drop weight on yourself
Weight stack	Easy to set down if needed
No spotter needed	Safe to train to failure
Seated position	Stable, low fall risk

Safe Failure

How to safely reach failure on machine press:

1. Let weight stack down gently — when you can't complete a rep, simply stop pushing
2. No need for bail-out — the machine controls the weight
3. Reset and rest — re-rack is automatic, just release handles

Perfect for Beginners

One of the safest exercises for learning pressing to failure. The machine guides the path and you can't get pinned under a bar.

🦴 Joints Involved

Joint	Action	ROM Required	Stress Level
Shoulder	Horizontal adduction, flexion	Moderate 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	Pain-free horizontal pressing	Can press handles forward without discomfort	Reduce ROM, adjust seat
Thoracic	Upright seated posture	Can sit tall without rounding	Work on thoracic extension
Wrist	Neutral grip strength	Can grip handles without pain	Adjust handle position

Joint-Friendly Design

The fixed path and seated position make this one of the most joint-friendly pressing exercises. Good option for those with mild shoulder issues (after medical clearance).

❓ Common Questions

How do I know if the seat height is correct?

When seated with handles at rest position, they should be level with your mid-chest (nipple line). If handles are too high, you'll press upward (more shoulder). Too low and you'll press downward (awkward angle). Most people need seat 3-5 holes from the bottom.

Should I lock out my elbows completely?

Yes — full elbow extension is safe and recommended. Don't hyperextend (pushing past straight), but do straighten arms completely. This ensures full ROM and complete muscle contraction.

When should I progress from machine to free weights?

When you can press 0.75-1x your bodyweight for 10+ controlled reps with excellent form. Also ensure you have good shoulder stability and no pain. Transition to Dumbbell Bench Press first before Bench Press.

Should my back stay flat against the pad?

Yes — unlike free weight bench press, there's no need to arch. Keep your entire back in contact with the backrest. This removes the stability component and lets you focus purely on pressing.

How do I prevent shoulder pain?

Key points: proper seat height (handles at mid-chest), keep shoulder blades back against pad, avoid flaring elbows out to 90°, and don't let shoulders roll forward. If pain persists, try neutral grip or reduce ROM.

For Mo

When to recommend this exercise:

• User is a beginner learning pressing movements
• User wants to train to failure safely without a spotter
• User has mild shoulder issues (machine path may be more comfortable)
• User wants hypertrophy work after heavy free weight compounds

Who should NOT do this exercise:

• Acute shoulder injury → Suggest rest and rehabilitation
• No machine access → Suggest Push-Up or Dumbbell Bench Press
• Advanced lifter seeking max strength → Suggest Bench Press

Key coaching cues to emphasize:

1. "Chest to the ceiling" (maintains upright posture)
2. "Shoulder blades glued to the pad"
3. "Push the machine through the wall"

Common issues to watch for in user feedback:

• "I don't feel my chest" → Check seat height, cue squeeze at top, slow eccentric
• "My shoulders hurt" → Verify seat height, ensure shoulder blades stay back, try neutral grip
• "It feels too easy" → Time to progress to dumbbells or increase volume
• "My back arches off the pad" → Cue core bracing, feet planted, back flat

Programming guidance:

• Pair with: Horizontal pull (rows), vertical press, tricep isolation
• Avoid same day as: Multiple other chest pressing (causes overlap fatigue)
• Typical frequency: 2x per week for beginners
• Transition marker: When pressing 1x bodyweight for 10 clean reps, ready for free weights

Progression signals:

• Ready to progress when: Consistent 12-15 reps at top of weight stack, or pressing bodyweight
• Add weight: 5-10 lbs per session for beginners
• Progress to free weights: When confident, strong, pain-free
• Regress if: Shoulder pain develops, form consistently breaks down
