Assisted Pull-Up Machine: how to do it right
In short: The machine-assisted pull-up targets back width, with maximum tension at mid-range of the pull.
How to do it, step by step
- 1Set the assistance, place knees or feet on the pad and take an overhand grip slightly wider than the shoulders.
- 2Start with long arms, shoulders down, brace the trunk without arching the lower back.
- 3Pull the elbows down and back, bringing the chest toward the bar, without swinging.
- 4Make a short contraction at the top without craning the neck up too high.
- 5Control the phase where the back lengthens, stay tense until the full stretch without losing tension.
The mistake to avoid
Don't cut the range short, lower to straight arms on every rep.
Other common mistakes
- Pulling with the arms and shoulders rising toward the ears: instead keep the shoulder blades down and start with the elbows.
- Using momentum from the legs or torso: keep the body still and let the assistance make up the strength difference.
- Going up too fast without controlling the stretch: brake the phase where the back lengthens to keep tension continuous.
- Choosing too much assistance, which removes the effort: dose the load to stay challenged at mid-range.
Muscles worked
- Main:
- Back (width)
- Supporting:
- Biceps
The lats are the prime mover, they pull the arm toward the trunk and create width. The teres major assists at the start of the pull. The lower trap fibers and rhomboids stabilize the shoulder blades. The biceps brachii and brachialis flex the elbow as secondary movers. The assistance pad or step takes off part of your body weight to make the movement accessible.

Frequently asked questions
How do I do this exercise?
Set the assistance, place knees or feet on the pad and take an overhand grip slightly wider than the shoulders. Start with long arms, shoulders down, brace the trunk, then pull the elbows down and back, bringing the chest toward the bar. Control the lowering until the full stretch without losing tension.
How low should I go?
Start with long arms at the bottom and rise until the elbows pass rib level, that's where tension peaks. Don't rush this middle by speeding up: slow down when it gets hard. No need to wriggle to get to the bar at the top, go for the full range you can control.
I don't feel anything, is that normal?
You should feel the work in your back, not in the biceps. Don't think hands, think elbows: imagine you're pulling your elbows toward your hips, not the bar toward you. That recruits the lats before the biceps. Slow down clearly through the middle of the movement, where tension peaks.
How fast should I do the movement?
Brake the lowering as the arms lengthen over 2 to 3 seconds, then pull crisply but in control. The braking and the control of the middle do the work, not speed.
How do I breathe?
Inhale in the low position with long arms, exhale as you pull your body up through the sticking point. Keep the trunk braced and abs tight from start to finish to avoid swinging and protect the lower back.
