How to do it

Weighted pull-up with a dip belt to progress in strength. Rise with control driving the elbows down and back until the chin clears the bar, no kipping; lower to full arm extension.

Muscles worked

Main muscle: back. Also worked: biceps. When it plans weekly volume, the generator counts each set of this exercise as one full set for back and half a set for each secondary muscle (what is known as fractional counting).

Weighted pull-ups: when bodyweight is no longer enough

Compared with bodyweight pull-ups, the difference is external overload: with a belt or a vest the sets drop to a few reps, three to six is a common range, and the exercise becomes strength work that progresses in pounds. Increments should be small, because every extra plate shows. They also ask more of your grip, elbows and shoulders, and tendons adapt more slowly than muscle, so progression has to be patient. Compared with the lat pulldown, you can't adjust the load with a pin: you depend on the plates you have.

Save them for when regular pull-ups come with full range and reps to spare, across several sets. Warm up with sets without weight and choose the setup that suits you: a belt with a chain, a weighted vest, or a dumbbell held between your feet, the last one being the least comfortable. To progress, put full range first before adding weight, and add small plates.

The weight hangs and tends to swing: use a short chain, set it close to your body, and pull up without oscillating. Brake at the start of the descent so you don't let the weight drop suddenly onto your elbows and shoulders.

Recommended sets and reps

As a compound lift, it fits in 3–5 sets of 5–12 reps leaving 1–3 reps in reserve (RIR). Prioritize it at the start of the session, when you're fresh.

Common mistakes to avoid

What the research says

This is a multi-joint lift, and with these the rep range matters less than it seems: Schoenfeld and colleagues (2021) concluded that muscle growth is similar with heavy or moderate loads as long as sets end close to failure, while maximal strength improves more with heavy loads.

Its peak tension comes with the muscle stretched, and that matters: in the trial by Maeo and colleagues (2021), seated leg curls, which stretch the hamstrings more, built more muscle than lying curls, and Pedrosa and colleagues (2022) saw something similar in the quads when training the long end of the range.

On how hard to push: the meta-analysis by Refalo and colleagues (2023) found no clear advantage in going to failure over stopping just short of it. That is why the generator programs it with reps in reserve (RIR) instead of asking for failure on every set.

How Weighted pull-ups compares with other back exercises

Of the 18 back exercises in the catalogue, ranked from least to most fatiguing by the values the generator uses, Weighted pull-ups is number 16.

With that fatigue it is best placed early in the session, while you are fresh, without stacking equally demanding exercises for the same group after it.

With different equipment, the same movement pattern offers 2 alternatives, such as Lat pulldown and Neutral-grip lat pulldown.

Tension with the muscle stretched. Weighted pull-ups loads the muscle when it is longest. In the review by Kassiano et al. (2023), across eleven studies, full range of motion and partials performed in the initial part of the movement — with the muscle long — produced more growth than partials performed at the end.

Bodyweight. In the trial by Kotarsky et al. (2018), four weeks of progressively harder push-ups significantly improved bench press 1RM, just like training the bench press itself. It is a strength result, not a hypertrophy one, and the condition is the word progressive: the exercise has to keep getting harder.

Frequently asked questions

What muscles does Weighted pull-ups work?

Weighted pull-ups mainly works the back muscle group, plus synergist and stabilizer muscles depending on the variation.

How many sets of Weighted pull-ups should I do?

Between 3 and 5 sets per session, adjusting the total weekly volume for back to your level (about 10–20 sets per muscle per week).

Belt, vest or dumbbell between the feet for weighted pull-ups?

A belt with a chain is the most common, since you can add plates easily and the weight sits near your hips. A vest spreads the load over your torso but caps the maximum weight. A dumbbell between the feet works in a pinch, though it's awkward and swings. Pick the one that lets you pull up without oscillating.
