How to do it

With the high pulleys at your sides, flex the elbows bringing the hands toward your ears, arms out in a T. It works the biceps in its shortest position; keep the elbows high and still.

Muscles worked

Main muscle: biceps. When it plans weekly volume, every set of this exercise counts in full for biceps: the generator does not split it with other muscles.

Overhead cable curl versus low cable curl: where the tension concentrates

Both versions use a cable, but they load different parts of the range. The Low cable curl keeps tension from the bottom, with the arm almost straight. In the overhead cable curl your arms are out to the sides at shoulder height, like a bodybuilding pose, and the cable pulls outward: the most demanding stretch is at the top, with the biceps shortened and the elbows high. It is a finishing exercise more than an overload exercise, which is why light loads make sense.

You need two high pulleys or a cable crossover. Stand in the middle with the cables at hand height and keep your elbows at shoulder level. It is a good choice for the end of a session, when you want an intense contraction. If there is no crossover, use the low cable curl instead.

One detail specific to this curl: squeeze at the top for a moment, as in a biceps pose, and do not let your elbows sink as you tire, because then it turns into an ordinary curl. Add weight only when the elbows stay high on every rep.

Recommended sets and reps

As an isolation exercise, it works best in 3–4 sets of 10–15 reps with 0–2 RIR. Use it at the end of the session to add volume without systemic fatigue.

Common mistakes to avoid

What the research says

As an isolation move, it is mostly a way to add volume to one muscle. Gentil and colleagues (2013) found that, in beginners, adding it to a multi-joint exercise gave no extra arm growth; it pays off later on, or for muscles the compounds barely reach.

It loads the muscle in the stretched position, which is where several trials find more growth: more hypertrophy from seated than lying leg curls (Maeo and colleagues, 2021) and better quad results from training the long part of the range (Pedrosa and colleagues, 2022). So do not cut the bottom of the rep short.

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 Overhead cable curl compares with other biceps exercises

Of the 16 biceps exercises in the catalogue, ranked from least to most fatiguing by the values the generator uses, Overhead cable curl is number 4 (tied with 9 others).

That makes it a good candidate for adding biceps sets at the end of a session or in heavy weeks, when you want volume without extra fatigue.

With different equipment, the same movement pattern offers 13 alternatives, such as Band concentration curl, Resistance band biceps curl and Band hammer curl.

Tension with the muscle stretched. Overhead cable curl 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.

An isolation exercise. In the trial by Gentil et al. (2015), with untrained young men over ten weeks, the biceps curl and the lat pulldown were equally effective for gaining strength and size in the elbow flexors: isolation is not filler.

Frequently asked questions

What muscles does Overhead cable curl work?

Overhead cable curl mainly works the biceps muscle group, plus synergist and stabilizer muscles depending on the variation.

How many sets of Overhead cable curl should I do?

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

How much weight should I use on the overhead cable curl?

Quite a bit less than on a standing curl. Choose a load you can lift for ten to fifteen reps with your elbows at shoulder level, without them dropping or drifting forward. If they sink, you are turning it into a different exercise and the load is too heavy.
