How to perform Kneeling Cable Triceps Extension
- Place a bench sideways in front of a high pulley machine.
- Hold a straight bar attachment above your head with your hands about 6 inches apart with your palms facing down.
- Face away from the machine and kneel.
- Place your head and the back of your upper arms on the bench. Your elbows should be bent with the forearms pointing towards the high pulley. This will be your starting position.
- While keeping your upper arms close to your head at all times with the elbows in, press the bar out in a semicircular motion until the elbows are locked and your arms are parallel to the floor. Contract the triceps hard and keep this position for a second. Exhale as you perform this movement.
- Slowly return to the starting position as you breathe in.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Triceps (primary): straightens the elbow to lock out every press and pushdown.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Fix the elbows in place and let only the forearms move, keeping the load on the triceps.
- Keep tension on the cable through the whole range — pause before the stack touches down instead of letting it crash.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Letting the elbows flare and drift forward so the shoulders quietly take over.
- Letting the stack yank the working muscle back at the end of each rep.
- Chasing weight jumps before the current load feels solid on every rep.
