Description
The cable triceps pushdown is the bread-and-butter isolation for the triceps — the muscle that makes up roughly two thirds of upper-arm size. Standing at a high pulley, you extend the elbows against constant cable tension while the upper arms stay pinned, isolating all three triceps heads with a resistance curve that stays smooth from stretch to lockout. It is easy to learn, easy to load precisely, and easy on the elbows, which is why the pushdown anchors the triceps work in everything from beginner programs to advanced arm specialization blocks.
How to perform
- Set up at a high pulley Attach a straight or angled bar to a high cable. Grip it shoulder-width, palms down, and step back half a step.
- Pin your elbows to your sides Tuck your upper arms against your torso with a slight forward lean from the hips, core braced — the elbows stay glued there all set.
- Push down to full lockout Drive the bar down by straightening your elbows until your arms are completely extended, without the shoulders rolling forward.
- Squeeze the triceps hard At lockout, contract the triceps deliberately for a beat — the last few degrees of extension are where they work hardest.
- Return with control Let the bar rise slowly until your forearms pass parallel to the floor and you feel a stretch in the triceps.
- Stay rigid between reps Keep the torso angle and elbow position identical on every rep — only the forearms travel.
Tips
- A slight, fixed forward lean is correct setup, not cheating — set it once and freeze it, because the fault is leaning more as fatigue builds.
- Think of the hands as hooks and push the bar down with the back of your arms — chasing the lockout squeeze beats chasing stack weight.
- Swap to a rope to extend the range: pulling the ends apart at the bottom adds a longer contraction than any straight bar allows.
- Let the bar travel high enough to stretch the triceps each rep — short pump reps in the bottom half leave growth on the table.
- If the weight bends you forward as you press, drop one or two plates — torso movement is load the triceps never see.
Common mistakes
- Letting the elbows drift forward and back — turning the pushdown into a pseudo bench press recruits chest and shoulders and unloads the triceps.
- Leaning harder as the set progresses — pressing with bodyweight instead of arm strength is the most common pushdown cheat in every gym.
- Stopping short of lockout — the triceps' peak contraction lives in the final degrees of extension; skipping them removes the best part of the rep.
- Cutting the top range — releasing the bar only a few inches keeps tension off the stretched triceps and halves the effective range of motion.
- Rolling the shoulders forward at the bottom — protraction sneaks the chest into the finish and signals the load is too heavy for strict reps.
Recommended sets & reps
| Sets | Reps | RIR | |
|---|---|---|---|
| Strength | 3–4 | 8–10 | 1–2 |
| Hypertrophy | 3–4 | 10–15 | 1–2 |
| Endurance | 2–3 | 15–20 | 2–3 |
| Power | 3 | 8–10 | 2–3 |
These ranges are working sets only — add 1–2 progressive warm-up sets before each working set. Pair with 2× per week frequency to reach ~10–20 weekly sets per muscle group, the volume range supported by current evidence (Schoenfeld 2017, Pelland 2025).
Benefits
Isolates the triceps with constant cable tension through the full range — something free-weight extensions cannot replicate at the lockout, where the triceps contract hardest. Builds the arm size most lifters actually want, since the triceps dwarf the biceps in upper-arm volume. Elbow-friendly loading makes high weekly volumes sustainable, even for lifters whose joints complain about skull crushers. Stronger lockout strength transfers directly to the bench press and overhead press. Setup takes seconds and progression is precise to the smallest plate on the stack, making it the most repeatable triceps exercise in the gym.
Frequently asked questions
Which attachment is best for triceps pushdowns?
All of them work — they shift emphasis slightly. A straight bar allows the most load, the rope adds range and a harder squeeze at the bottom, and the V-bar sits between the two with a friendlier wrist angle. Rotating attachments across blocks covers every angle.
Why do I feel pushdowns in my shoulders or chest?
Your elbows are drifting or your shoulders are rolling forward at the bottom — both let bigger muscles take over. Lighten the load, pin the upper arms to your sides, and keep the chest tall through the lockout.
Are pushdowns enough for complete triceps development?
Almost. The long head of the triceps crosses the shoulder and only reaches a full stretch with the arm overhead, so pair pushdowns with an overhead extension or skull crusher. The two movement types together cover all three heads completely.
How much weight should I use on pushdowns?
Whatever allows a motionless torso, pinned elbows and a one-second lockout squeeze for every rep of the set. For most lifters that is 20–40 kg on the stack — and adding a single plate while keeping that standard is real progress.
