The cable incline triceps extension is an isolation exercise that targets the triceps brachii on the back of the upper arm. Performed on an incline bench facing away from a low cable pulley, it keeps constant tension on the triceps through the full range of motion, making it a strong finisher for building arm size and lockout strength.
How to do the Cable Incline Triceps Extension
- 1Set an adjustable bench to roughly a 45° incline and position it a couple of feet in front of a low cable pulley fitted with a rope or straight bar.
- 2Sit on the bench facing away from the machine and reach back to grip the attachment, then lie back so your torso rests against the pad.
- 3Press the attachment up until your arms are fully extended overhead, with your upper arms angled slightly back and pointing toward the ceiling.
- 4Keep your upper arms fixed in place and your elbows pointing forward as the stable pivot point.
- 5Lower the attachment behind your head by bending only at the elbows, feeling a stretch in the triceps.
- 6Pause briefly in the stretched position without letting your upper arms drift.
- 7Extend your elbows to drive the attachment back overhead until your arms are fully straight, squeezing the triceps at the top.
- 8Complete your reps, then return the attachment to the stack under control.
Form tips
- Keep your upper arms still and let only the forearms move, so the triceps do the work instead of the shoulders.
- Control the lowering phase rather than letting the cable pull your arms down, keeping tension on the triceps throughout.
- Use a weight you can fully lock out at the top; the squeeze at full extension is where the triceps work hardest.
- Set the bench far enough from the pulley that the cable line stays slightly behind you for constant tension.
Common mistakes
- Letting the elbows flare out and drift, which turns the movement into a shoulder press and takes load off the triceps.
- Using too much weight and shortening the range of motion, so you lose the deep stretch that drives triceps growth.
- Swinging the torso or arms to heave the weight up, which uses momentum instead of muscular tension and risks elbow strain.
- Stopping short of full lockout, which skips the strongest contraction the triceps can produce at the top.
Frequently asked questions
What muscles does the cable incline triceps extension work?
It is an isolation exercise that targets the triceps brachii, the muscle on the back of the upper arm responsible for straightening the elbow.
Why use an incline bench instead of doing this standing?
The incline bench supports your torso and locks your upper arms in place, so you can isolate the triceps without swinging, and the angle keeps tension on the muscle through a long stretch.
Is the cable incline triceps extension good for beginners?
Yes. The cable provides smooth, constant resistance and the bench supports your back, making it easier to learn strict form than free-weight overhead extensions.
How many sets and reps should I do?
As an isolation move, it suits moderate loads and higher reps. Three to four sets of 10 to 15 reps with controlled form works well for building the triceps.
