Tricep pushdown: rope or bar, where the elbows go, and the long-head question

A tricep pushdown is the cable exercise where you stand at a high pulley and press a rope or bar down until your arms are straight, with your elbows held at your sides. Only the elbow moves, so the work goes to the triceps, the muscle on the back of the upper arm. It has three heads, and one of them, the long head, crosses the shoulder as well as the elbow, which is why the position of your arm matters for it.¹

This page covers the setup, rope against bar, where your elbows go, what the pushdown does and doesn't do for the long head, strict reps against a little momentum, the faults, and the sets. How triceps work fits next to your presses, and how to count it, is on the arm workout; the rest of a session on one cable station is on the cable workout.

How to do a tricep pushdown

1. Set the pulley high, above your head, and clip on a rope or a short bar.
2. Stand close and tall, feet about hip-width apart, with a slight forward lean at most. Take the handle with your elbows bent and tucked against your sides.
3. Press down until your arms are straight, moving only at the elbows.
4. Let your forearms come back up under control until your elbows are bent to about a right angle, then press again. Your upper arms stay where they are the whole set.

That range, from a right angle to straight, is the one the long-head trial below used.¹ In the momentum trial further down, the strict arm kept an upright torso and the upper arm still at the side, so the only movement was at the elbow.²

Rope or bar

No study comparing rope and bar pushdowns for triceps activity or growth turned up in a PubMed search for this page, so the choice comes down to how each one sits in your hands and on your wrists.

The momentum trial below trained one arm at a time with the palm facing down.² Pick the handle that lets your elbows stay still and your wrists stay straight, and keep it long enough to add weight to it.

Where the elbows go

Pinned to your sides, or just in front of them, and still. Two things happen when they move:

• Elbows drifting forward and up as the handle rises: the shoulder starts to help, and the rep stops being only an elbow movement. Lighten the weight and bring the elbows back to your ribs.
• Elbows flaring out as you press: the pushdown turns into a short press, with the chest and shoulders joining in. Keep them about as wide as your torso.

Where your upper arm sits does change the triceps work, but that's a choice of exercise, not a fault in this one. It's the long-head question.

The long-head question: pushdown or overhead extension

The long head is the triceps head that crosses the shoulder, and it's stretched more when your arm is overhead than when it's down at your side.¹ One trial tested whether that matters for growth. In 21 adults over 12 weeks, one arm did cable triceps extensions overhead and the other did them with the arm down at the side, both through the same range. The overhead arm's whole triceps grew 19.9% against 13.9%, and its long head 28.5% against 19.6%, even though that arm lifted lighter weights.¹

Read it both ways. The arm at the side still grew, the long head included (+19.6%), and so did the lateral and medial heads together (+10.5%). In 25 untrained young men doing pushdowns to failure, electrodes recorded all three heads working, and they tired at comparable rates, though the authors found they didn't work in unison.³ That's activity during a set, not growth. But the overhead position grew more. That's why the arm workout puts the overhead extension first: if you only have room for one triceps exercise, make it the overhead one, and keep the pushdown as the second.

Your presses count too. In 13 healthy men who bench pressed three times a week for ten weeks, the triceps grew more than in 11 men who didn't train,⁴ and in a 2026 meta-regression, the counting method with the strongest evidence scored a set that trains a muscle only indirectly as half a set.⁵ So a week of pressing already gives the triceps part of its work; the pushdown adds direct sets on top.

Strict reps or a little momentum

One trial tested this on the pushdown itself. Of 30 untrained young adults who started, 25 finished, 11 men and 14 women. Each trained one arm with strict pushdowns and curls and the other with momentum on every rep (on the pushdown: elbows flaring, a knee bend and a forward lean), four sets of 8 to 12 to failure, twice a week for eight weeks. The arm muscles grew similarly either way, although the momentum arm lifted about twice the volume load (weight times reps).²

So in untrained lifters, momentum neither helped nor hurt growth; the authors note the result may not carry over to experienced lifters. Strict reps are still the default, for a practical reason: a rep done the same way every time is one you can compare from week to week, which is how you can tell you're getting stronger.

The common faults, and a fix for each

• Elbows drifting forward. They should finish each rep where they started, at your sides.
• Leaning over the handle and pushing with your body weight. Stand closer and taller, and lighten the weight. In the trial above the momentum arm still grew, so the set isn't wasted, but a heave that changes from rep to rep can't be compared from week to week.
• Stopping short of straight. Press until your arms are fully straight; half reps leave out the end of the range.
• Letting the handle fly up. Control the way back. If your hands rise toward your chest and your elbows lift, the weight is pulling your upper arms out of position.
• Bending your wrists back on a straight bar. Switch to an angled bar or a rope.
• Pressing through something that hurts. Sore the next day is normal; a sharp or lasting hurt in the elbow isn't. Stop, and see a doctor or a physical therapist.

No cable? Alternatives

• An overhead dumbbell extension, one dumbbell held in both hands behind your head: the overhead position from the trial above, with a dumbbell instead of a cable.
• A dumbbell kickback, bent over with your upper arm held along your side while the forearm straightens back: the same arm position as a pushdown. No study comparing it with the pushdown turned up in the search for this page.
• A band pushdown, with a band anchored over a door or a pull-up bar: the same movement at home.

Sets, reps and where it goes

• Two or three sets of 10 to 15, after your presses, at the end of a push or upper-body day.
• Close to failure is fine. Isolation work is a good place to stop with zero or one rep left. (How to judge reps left.) The American College of Sports Medicine's 2026 position stand, which covers healthy adults, advises at least two sets per exercise.⁶
• Next to the overhead extension, two sets of each covers both arm positions.
• Paired with a curl. On a cable station, a pushdown and a preacher curl make an easy pair: one set of each, then rest. On an upper-body day they come after the chest press machine and the rear delt fly.
• Add weight when every set reaches 15. Cable stacks often jump in big steps, so add reps until you can take the next pin. (Progressive overload covers how.)

If you'd rather not plan it alone

A pushdown is easy to learn; deciding how much direct triceps work your week needs on top of the pressing you already do is the part a page can't do. Coaching is the version where your workouts are built around the days you actually have, and a weekly call looks at the week you just had and rebuilds the next one. Coaching to build muscle explains how that works, and here's how to apply. Otherwise: at your next upper-body session, do two sets of pushdowns after your presses and write down the weight.
