🎯 Setup

Starting Position

1. Set assistance weight: Select counterweight on machine
   • More weight = easier (machine assists more)
   • Less weight = harder (closer to bodyweight)
   • Start with assistance of 50-70% of your bodyweight
2. Grip: Choose your grip style
   • Overhand (pull-up): Lats emphasis
   • Underhand (chin-up): More biceps
   • Neutral: Shoulder-friendly middle ground
3. Hand position: Grip width slightly wider than shoulders (for overhand)
4. Mount platform: Carefully step or kneel onto assistance platform
   • Keep platform stable, don't bounce
5. Body position: Hang with arms extended, core engaged
   • Shoulders packed down (not shrugged)
   • Slight hollow body position

Equipment Setup

Equipment	Setting	Notes
Assistance Weight	50-70% bodyweight to start	Higher weight = easier
Grip Type	Overhand, underhand, or neutral	Depends on goal
Grip Width	Shoulder-width to slightly wider	Standard pull-up width
Platform	Knees or feet	Most use kneeling position

Setup Cue

"Set assistance weight higher than you think you need — master the movement pattern first, then reduce assistance"

🔄 Execution

The Movement

🔧 Setup Phase

What's happening: Setting up for assisted pull with proper assistance

1. Select assistance weight on machine
2. Grip handles with chosen grip (overhand, underhand, or neutral)
3. Step or kneel onto assistance platform
4. Let platform support you in hanging position
5. Engage scapula — pull shoulder blades down and back
6. Brace core, take a breath

Tempo: Controlled setup, establish stability

Feel: Platform supporting your weight, shoulders engaged, ready to pull

⬆️ Pull Phase

What's happening: Pulling chest toward bar with machine assistance

1. Initiate pull by driving elbows down and back
2. Think "pull elbows to hips/ribs" not "pull hands"
3. Let the assistance help, but actively engage your back
4. Pull until chin clears handles (or chest to bar for full ROM)
5. Breathing: Exhale during the pull

Tempo: 1-2 seconds (controlled, powerful)

Feel: Lats and biceps working, machine assisting but YOU are pulling

Critical: Don't let the machine do all the work — actively engage your muscles

🔝 Top Position

What's happening: Peak contraction, chin above handles

1. Chin clears the handles, chest near bar
2. Elbows pulled down and back
3. Scapula fully retracted
4. Brief pause (0.5-1 second)
5. Squeeze your back at the top

Common error here: Rushing through top position. Pause and squeeze.

⬇️ Lowering

What's happening: Controlled descent with assistance

1. Lower yourself with control — don't drop
2. The machine assists, but YOU control the speed
3. Maintain core tension throughout
4. Extend arms fully at bottom
5. Return to active hang position
6. Breathing: Inhale on the way down

Tempo: 2-3 seconds (controlled eccentric)

Feel: Resisting gravity with machine support, feeling the stretch in lats

Note: Control the eccentric even with assistance — this builds strength

Key Cues

Primary Cues

• "Drive elbows down and back" — engages lats properly
• "You pull, machine assists" — don't let machine do all the work
• "Chest to bar" — ensures full range of motion

Tempo Guide

Goal	Tempo	Example
Learning Pattern	2-1-2-1	2s up, 1s pause, 2s down, 1s hang
Strength	1-0-2-1	1s up, no pause, 2s down, 1s hang
Hypertrophy	2-1-3-1	2s up, 1s pause, 3s down, 1s hang

⚠️ Common Mistakes

Mistake	What Happens	Why It's Bad	Fix
Too much assistance	Machine does all the work	Doesn't build strength toward unassisted pull-up	Use least assistance you can handle for 8-12 reps
Bouncing on platform	Using momentum to assist the pull	Reduces muscle engagement, inconsistent resistance	Maintain steady pressure on platform
Partial reps	Not achieving full ROM	Limits strength development	Full arm extension at bottom, chin over bar at top
Letting machine do everything	Passive pulling	Won't build real pull-up strength	Actively engage — YOU pull, machine just assists
Not progressing	Staying at same assistance weight	No adaptation, no progress	Reduce assistance by 5-10 lbs every 1-2 weeks

Most Common Error

Using too much assistance for too long — the goal is to progress to unassisted pull-ups. Reduce assistance weight progressively. If you can do 12+ reps comfortably, reduce the assistance.

Self-Check Checklist

• Using minimum assistance needed for 8-12 quality reps
• Full arm extension at bottom (no partial reps)
• Chin clears bar at top (or chest to bar)
• Actively pulling, not passively letting machine do it
• Reducing assistance weight over time

Upper body day	After compound press	When fresh enough for quality
Full-body	After lower body work	Upper body focus block
Beginner program	Early in workout	Learn pattern when fresh

Assistance Machine Notes

The assisted pull-up machine is a tool for progression, not a permanent solution. Your goal should be to reduce assistance over time and eventually transition to unassisted pull-ups or chin-ups.

Frequency

Training Level	Frequency	Volume Per Session
Beginner	2-3x/week	3-4 sets, 8-12 reps
Intermediate (progressing)	2-3x/week	4-5 sets, varied rep ranges
Advanced (using as accessory)	1-2x/week	3 sets, high reps for volume

Progression Scheme

Progressive Overload

Reduce assistance by 5-10 lbs when you can complete 3x12 reps with good form. Track your assistance weight and aim to reduce it every 1-2 weeks. Once you're using less than 20 lbs of assistance, transition to unassisted pull-ups (even if it's just 1-2 reps).

Sample 12-Week Progression

Week	Assistance (% BW)	Sets x Reps	Notes
1-2	60%	3x8-10	Learn movement, build base
3-4	50%	3x10-12	Reduce assistance, maintain reps
5-6	40%	4x8-10	Increase sets, moderate assistance
7-8	30%	4x8-10	Continue reducing assistance
9-10	20%	4x6-8	Getting close to bodyweight
11-12	10% or none	5x3-5	Transition to unassisted

🛡️ Safety & Contraindications

Who Should Be Careful

Condition	Risk	Modification
Shoulder impingement	Overhead position can aggravate	Use neutral grip, reduce ROM if needed
Knee discomfort	Kneeling on platform	Use foot platform if available, or pad the knee pad
Lower back issues	Arching excessively	Engage core, maintain neutral spine
Wrist pain	Grip pressure	Use neutral grip handles if available

Stop Immediately If

• Sharp pain in shoulder (not muscle fatigue)
• Knee pain from platform pressure (adjust padding or position)
• Inability to control the movement
• Platform feels unstable or unsafe
• Popping or clicking in shoulder joint

Injury Prevention

Strategy	Implementation
Proper warm-up	Scapular pull-ups, dead hangs, band pull-aparts
Start with higher assistance	Learn pattern before adding challenge
Full ROM	Don't short-change bottom or top position
Controlled tempo	No rushing or using momentum
Progress gradually	Reduce assistance slowly (5-10 lbs at a time)

Machine Safety

• Check weight stack: Ensure pin is secure before starting
• Platform stability: Make sure platform moves smoothly
• Don't bounce: Maintain steady pressure on platform
• Dismount carefully: Control the platform when getting off
• Adjust for height: Make sure handles are at appropriate height

Common Issue

Knee discomfort from platform — many machines have a hard knee pad. Consider placing a towel or pad for comfort, or use the foot platform option if available.

Shoulder	Extension, Adduction	180° overhead reach	🟢 Low-Moderate
Elbow	Flexion	140-150° flexion	🟢 Low-Moderate
Scapula	Depression, Retraction	Full scapular mobility	🟢 Low-Moderate
Wrist	Stabilization	Neutral position	🟢 Low

Mobility Requirements

Joint	Minimum ROM	Test	If Limited
Shoulder	180° overhead flexion	Can reach arms fully overhead	Shoulder mobility drills, wall slides
Scapula	Full retraction/depression	Can squeeze shoulder blades together	Scapular pull-ups, band pull-aparts
Thoracic	Good extension	Can extend upper back	Foam roll thoracic spine, cat-cow

Joint Health Note

The assisted pull-up machine is generally very joint-friendly due to the assistance reducing load. It's an excellent option for building pulling strength while minimizing joint stress.

❓ Common Questions

How much assistance should I start with?

Start with 50-70% of your bodyweight in assistance. This should allow you to complete 8-12 reps with good form. It's better to start with more assistance and reduce it than to struggle with too little assistance and develop bad habits.

How do I know when to reduce the assistance?

Reduce assistance by 5-10 lbs when you can complete 3 sets of 12 reps with perfect form. If you're comfortable and reps feel controlled, it's time to make it harder.

Will I ever be able to do unassisted pull-ups?

Yes! Consistent training 2-3x per week with progressive reduction in assistance will get you there. Most people can achieve their first unassisted pull-up within 8-16 weeks of dedicated training. Be patient and trust the process.

Should I use overhand or underhand grip?

Both are valuable:

• Overhand (pull-up grip): Harder, more lat emphasis — if your goal is pull-ups
• Underhand (chin-up grip): Easier, more biceps — great for building initial strength
• Neutral grip: Most shoulder-friendly, balanced

Start with whichever grip matches your goal exercise.

The knee pad hurts my knees. What should I do?

Common solutions:

1. Place a towel or foam pad on the knee platform
2. Use the foot platform if your machine has one
3. Adjust your body position slightly
4. Some machines have adjustable padding — check if yours does

If pain persists, try band-assisted pull-ups instead.

Can I build muscle with assisted pull-ups or do I need to do unassisted?

You can absolutely build muscle with assisted pull-ups, especially in the 8-12 rep range with moderate assistance. However, your goal should be to progressively reduce assistance. The process of getting stronger IS what builds muscle.

How is this different from lat pulldowns?

Assisted pull-ups more closely mimic the real pull-up movement pattern and require more core stability. Lat pulldowns allow for easier weight adjustments and can be loaded heavier. Both are valuable — assisted pull-ups are better for pull-up progression, lat pulldowns are better for pure lat hypertrophy.

For Mo

When to recommend this exercise:

• User cannot do unassisted pull-ups or chin-ups yet
• User wants to build toward first pull-up
• User has access to assisted pull-up machine
• User is new to vertical pulling movements

Who should NOT do this exercise:

• Acute shoulder injury → Wait until healed or use Lat Pulldown
• Severe knee pain from platform → Try Band-Assisted Pull-Up instead
• No access to machine → Recommend Band-Assisted Pull-Up or Lat Pulldown

Key coaching cues to emphasize:

1. "Use the least assistance you need for 8-12 quality reps"
2. "YOU pull, the machine just assists — stay active"
3. "Full ROM — arms straight at bottom, chin over bar at top"
4. "Reduce assistance every 1-2 weeks as you get stronger"

Common issues to watch for in user feedback:

• "Using too much assistance for too long" → Encourage progressive reduction
• "Bouncing on platform" → Cue steady pressure, no momentum
• "Not feeling it in the right muscles" → Check scapular engagement and grip type
• "Knee pain from platform" → Suggest padding or foot platform alternative

Programming guidance:

• Pair with: Horizontal pulls (rows), pushing movements, core work
• Avoid same day as: Excessive lat isolation afterward (save energy for this exercise)
• Typical frequency: 2-3x/week for optimal progression
• Place early in workout when fresh

Progression signals:

• Ready to reduce assistance: Can complete 3x12 with perfect form
• Ready to transition to unassisted: Using less than 10-20 lbs assistance
• Consider alternatives if: Stalling for 4+ weeks at same assistance level

Red flags:

• Using same assistance weight for months → not progressing
• Partial ROM (not full extension or not chin over bar) → ego lifting
• Sharp shoulder pain → assess injury
• Excessive swinging or momentum → form breakdown
