The best assisted pull-up for most people is a band-assisted pull-up at home or the counterweight machine at the gym. Both let you work through a full rep before you can lift your own bodyweight, and both make it easy to reduce the help week by week. Below you'll find how to do each one, the other ways to get assistance, which mistakes hold people back, and a 6 week plan to wean yourself off the help.
Every method does the same job: it takes some of your bodyweight off the bar so you can complete the movement.
If you train at home, bands are the obvious choice. At the gym, start on the machine, then move to bands once you need less than about a quarter of your bodyweight in help.
You'll need a sturdy bar and a long loop band, usually around 2m. If you haven't got a bar yet, our guide to the best pull-up bars in the UK covers doorway and wall-mounted options.
Watch the top half
A band helps most where it's most stretched, at the bottom. That means the top few inches feel much harder than the start. If you keep stalling with your chin just under the bar, add a 1 to 2 second pause at the top of each rep to build strength exactly where you're weakest.
The machine gives you a number, which is its biggest advantage. When you write down "30kg assistance, 3 sets of 8", you know exactly what to beat next session.
An assisted pull-up works the same muscles as a full one, just with less load.
Grip choice matters less than you'd think. An electromyography study of 19 trained men found overall activation of the shoulder, arm and forearm muscles was similar across overhand, underhand, neutral and rope pull-ups, although the overhand grip worked the middle trapezius harder (Dickie et al., 2017). The same study found the biceps, brachioradialis and chest were more active on the way up than the way down. So pick the grip that feels best on your shoulders and focus on the pulling phase.
The aim is to give yourself a little less help every week or two while your reps stay the same or go up.
On bands. Most sets come in five colours, each covering a resistance range. Once you can do 3 sets of 8 to 10 clean reps, move down one band. If the jump feels too big, use the thinner band for your first set and the thicker one for the rest, or switch from knee to foot (a straight leg gets less help from the same band).
On the machine. Drop the assistance by 2.5kg to 5kg once you hit 3 sets of 8 to 10. Small steps keep you moving; big ones tend to stall you for weeks.
Rep targets that signal you're ready. When you can do 3 sets of 8 with your lightest band, or with roughly 10% to 15% of your bodyweight in machine assistance, try a single unassisted rep at the start of a session while you're fresh.
Adding negatives speeds things up too. In a 5 week study of advanced climbers training pull-ups twice a week, the eccentric-focused group improved maximal strength and pulling speed, while the untrained control group didn't change (Vigouroux and Devise, 2024). Those were experienced athletes, not beginners, but slow lowering is cheap to add and the plan below includes it.
If you want a set built for this job, the FitBeast five-band set covers five clearly marked levels, from 5 to 15lb up to 50 to 125lb. Each loop is 208cm long, and the set comes with a door anchor and a carry bag. It was around £31.99 at the time of writing.

Bouncing out of the band. Dropping fast and letting the band catapult you back up turns the exercise into a trampoline. Control the lower and pause briefly at the bottom.
Too much assistance for too long. If you're still doing 15 easy reps on the thickest band after a month, the band is doing your pull-up for you. Drop down a level, even if your reps fall to 5 or 6.
Shrugging up. Pulling with your shoulders around your ears puts the load on your upper traps and pinches the front of the shoulder. Set your shoulder blades down before the elbows move.
Kicking and swinging. Leg drive steals work from your back. Keep your legs straight and still, and squeeze your glutes if you tend to swing.
Train this twice a week with at least two days between sessions. Do it at the start of the workout, after a short warm-up of band pull-aparts and scapular hangs.
| Week | Main work | Finisher |
|---|---|---|
| 1 | 3 sets of 6 to 8 assisted pull-ups, 2 second lower | 2 x 20 second dead hang |
| 2 | 3 sets of 8 to 10 at the same assistance | 2 x 25 second dead hang |
| 3 | Reduce assistance one step; 3 sets of 6 to 8 | 3 negatives, 3 to 5 second lower |
| 4 | 4 sets of 6 to 8 at the new level, 1 second pause at the top | 3 negatives, 5 second lower |
| 5 | Reduce assistance one step; 3 sets of 6 to 8 | 4 negatives, 5 second lower |
| 6 | 3 sets of 8 at the week 5 level, then test 1 unassisted rep | 2 x 30 second dead hang |
Rest 90 seconds to 2 minutes between main sets. If you miss the bottom of the rep range in a session, repeat that week rather than pushing on. Lat pulldowns make a sound second exercise on a gym day; our lat pulldown vs pull-up guide explains how they compare. The NHS recommends muscle-strengthening work on at least two days a week, so this plan fits easily into a normal routine.
Once you've got 5 or more strict reps, your next target could be a muscle-up. For more bodyweight and gym exercise guides, browse our workouts hub.
Yes. They let you train the full pull-up pattern through the whole range of motion before you can lift your own bodyweight, which is exactly what you need to build towards an unassisted rep. They're also useful for experienced lifters who want extra volume once they're too tired for clean bodyweight reps.
The machine is easier to learn on and lets you change the assistance in small, measurable steps. A band is cheaper, works on any bar at home, and keeps you hanging freely like a real pull-up. Its drawback is that it helps most at the bottom and least at the top, which is where most people get stuck.
Pick the lightest band, or the smallest counterweight, that lets you complete 3 sets of 6 to 8 clean reps with your chin clearing the bar. If you can't hit 6, add help. If you can do 12 easily, take some away.
It depends on your starting strength and bodyweight, but many beginners who train pulling twice a week see their first unassisted rep within 6 to 12 weeks. Heavier lifters and complete beginners often need longer, and that's normal.
The same muscles as a normal pull-up: mainly your lats, with the biceps, brachialis, middle and lower traps, rhomboids, rear delts and forearm grip muscles helping. Your core works to keep your body from swinging, especially on the band version.
