The assisted pull-up is a back-building strength exercise performed on a leverage (assisted pull-up) machine that counterbalances part of your bodyweight through a kneeling or foot platform. It primarily targets the latissimus dorsi, with help from the biceps-region elbow flexors, rear deltoids, and mid-upper traps. It's the go-to way to build the strength and pattern needed for a full bodyweight pull-up.
How to do the Assisted Pull-up
- 1Set the counterweight on the machine — a heavier weight gives more assistance, making the rep easier. Start with enough help to complete clean reps.
- 2Grip the overhead handles slightly wider than shoulder-width with an overhand grip, wrapping your thumbs around the bar.
- 3Step or kneel onto the assist platform and let it support you as your arms extend fully overhead.
- 4Brace your core and pull your shoulder blades down and back to set your starting position with arms straight.
- 5Pull your body up by driving your elbows down toward your ribs, leading with your chest until your chin clears the bar.
- 6Squeeze your lats and upper back at the top, keeping your shoulders away from your ears.
- 7Lower under control until your arms are fully extended again, resisting the assistance on the way down.
- 8Complete your reps, then step or kneel off the platform safely and let the weight stack settle.
Form tips
- Reduce the counterweight gradually over weeks so you're progressively carrying more of your own bodyweight toward an unassisted pull-up.
- Lead the pull with your back, not your hands — think of pulling your elbows into your sides rather than just bending your arms.
- Keep your chest up and avoid swinging or kipping; let the machine do the assisting, not momentum.
- Control the lowering phase fully — the eccentric is where much of the lat and grip strength is built.
Common mistakes
- Using too much counterweight, which makes the movement nearly effortless and stalls back and grip development.
- Pulling only with the arms and letting the shoulders shrug up, which shifts work off the lats and stresses the neck and shoulders.
- Cutting the range of motion short by not extending the arms at the bottom or not clearing the bar at the top, reducing the training effect.
- Yanking up fast and dropping down quickly, which uses momentum instead of muscle and removes tension from the back.
Frequently asked questions
What muscles does the assisted pull-up work?
It primarily works the latissimus dorsi, with the brachialis and brachioradialis (elbow flexors), rear deltoids, teres major and minor, infraspinatus, and the middle and upper trapezius assisting.
Is the assisted pull-up good for beginners?
Yes. The leverage machine offsets part of your bodyweight, so you can train the full pull-up pattern with good form before you can do an unassisted rep, then reduce the assistance over time.
How much assistance should I use?
Use just enough counterweight to complete your target reps with clean form and a slight challenge on the last rep. As you get stronger, lower the assistance to keep progressing toward a full pull-up.
How many sets and reps should I do?
Three to four sets of 6–12 reps is a solid range for building back strength. Reduce the counterweight as those reps become easy to keep the muscles challenged.
