Band-assisted pull-up

What it is

Loop a resistance band over the bar and pass one end through the other so it hangs in a loop. Put a foot or a knee in the loop, take your grip, and perform a pull-up. The band takes some of your bodyweight.

Thicker bands assist more. A knee in the loop is more stable than a foot; getting in and out takes practice and is the least dignified part of the exercise.

What it demands

The same movement as a pull-up at a reduced load.

But the reduction is not even, and this is the thing worth understanding before choosing it. A band assists most where it is most stretched — at the bottom, with your arms straight — and least at the top, where it has recoiled. For most people the top of a pull-up is the hardest part. So the band gives the most help where you need it least, and the least help where you are already failing.

That is a genuine mechanical limitation rather than a criticism of bands. It just means the assistance profile runs opposite to the difficulty profile.

What usually goes wrong

Bouncing out of the bottom. The band's recoil launches the first part of the movement and the repetition begins with momentum rather than effort.

Choosing a band so thick that it does most of the work. Easy to do and hard to notice.

Not progressing off it. The band is a step, and the step is only useful if the bands get thinner over time.

Setting up carelessly. A thick band under tension coming off a bar or off your foot is worth being deliberate about.

Where it sits

This is the most popular route to a first pull-up and it is not the one this site would put first — for the reason above. The negative pull-up trains the movement at full bodyweight throughout, including at the top where the difficulty actually is.

Bands remain genuinely useful here for accumulating repetitions once the movement is available, and for anyone who cannot yet control a descent at all. The inverted row is the other honest answer, and it scales continuously.
