Triceps Pushdown
The triceps pushdown is a cable isolation move where you drive a bar or handle down from a bent elbow to a straight one, working the triceps through a controlled range with constant tension from the cable. It's one of the more joint-friendly ways to add direct arm volume once your pressing work is done, since the cable keeps the load steady instead of letting momentum carry a dumbbell or barbell.
Why it works
Your triceps job is simple: straighten the elbow. A pushdown isolates exactly that action while the cable's constant resistance means the muscle stays under tension from the top of the rep to the bottom, unlike a free weight where gravity can unload the triceps at certain points in the arc. Keeping your upper arms pinned to your sides also removes your shoulders from the equation almost entirely, so nearly all the work lands on the triceps instead of being shared with your chest or delts. That isolation is also why the pushdown is a popular finisher: by the time you reach it, your shoulders and chest are usually already tired from pressing, and a move that doesn't need fresh shoulders to work well fits that spot in a session.
Set up
- Attach a straight bar to the high pulley and set the weight.
- Stand close to the machine, feet shoulder-width apart, with a slight forward lean at the hips.
- Grip the bar with your hands shoulder-width apart, palms facing down.
- Pin your upper arms against your ribs and bend your elbows to about 90 degrees.
How to do it
- Keeping your upper arms locked against your sides, push the bar straight down.
- Extend your elbows fully without letting your shoulders roll forward to help.
- Pause for a beat at full extension and squeeze your triceps.
- Let the bar rise back under control until your forearms are roughly parallel to the floor.
- Keep your wrists firm and straight throughout; don't let them bend to compensate.
- Repeat for the full set without letting your elbows drift away from your body.
Form cues
- Elbows glued to your ribs the whole set.
- Push down, don't lean down.
- Squeeze at the bottom.
- Control the bar back up.
Breathing: Exhale as you push the bar down, inhale as you let it rise back up.
Common mistakes
Letting the elbows drift forward and away from the body as the arms extend.
Fix: Keep your upper arms pressed against your ribs for the entire rep; if they swing forward, you're turning the move into a shoulder press.
Leaning the torso forward to add bodyweight into the push.
Fix: Keep a slight, fixed forward lean and drive the movement from the elbow joint instead of rocking your body down into the bar.
Using a weight heavy enough that the bar flies back up uncontrolled on the return.
Fix: Drop the load until you can control both the push and the return at the same speed.
Stopping short of full elbow extension at the bottom of every rep.
Fix: Finish each rep with a straight arm and a brief squeeze; a partial lockout trains less of the muscle's full range.
Setting the pulley too high or too low, which forces an awkward angle at the start of the rep.
Fix: Set the pulley so your forearms start roughly parallel to the floor with your elbows at about 90 degrees; adjust the height rather than compensating with your stance.
How to program it
- This is an isolation finisher, so place it after your main pressing work, not before it.
- Three or four sets of 10 to 15 reps is a solid range for building size without needing heavy loads.
- Because it's low-fatigue on the joints and nervous system, you can hit it twice in the same week if your arm volume elsewhere is light.
- Slow the eccentric down for a few reps at the end of a set when you want extra time under tension without adding weight.
- If your gym has more than one cable station free, alternate between the straight bar, rope, and V-bar across weeks to keep the elbows and wrists working through slightly different angles.
Safety notes
- Stop if you feel a sharp pinch at the elbow rather than muscle fatigue; that's a sign the load or range needs adjusting, not pushing through.
- Avoid locking the elbows out violently at the bottom of fast reps, which can jar the joint over many sets.

Frequently asked questions
How many sets and reps of triceps pushdowns should I do?
Three or four sets of 10 to 15 reps works well for most people, placed after your main pressing exercises as a finisher for the arms.
Straight bar, rope, or V-bar for triceps pushdowns?
The straight bar is the simplest starting point. The rope lets your wrists rotate at the bottom, which is gentler on cranky elbows, while the V-bar's locked neutral grip usually lets you handle a bit more weight.
Can I do triceps pushdowns without a cable machine?
Yes. A dumbbell triceps extension trains the same elbow-extension pattern and works fine when no cable station is free.
Why do my elbows hurt during triceps pushdowns?
Usually it's too much weight or letting the elbows flare away from the body, which puts awkward stress on the joint. Lighten the load, keep your upper arms locked to your sides, and stop short of a painful range.
