Cable Kneeling Triceps Extension

- Isolation
- Rep-based
- Upper arms
- Waist
This isolation exercise targets the triceps, specifically emphasizing the long head by placing the arms in an overhead position. Using a bench for elbow support eliminates momentum and provides a stable base for maximum mechanical tension.

Setup
- Attach a rope handle to a high cable pulley and place a flat bench a few feet in front of the machine.
- Kneel on the floor facing away from the machine, resting your elbows and the backs of your upper arms on the end of the bench.
- Grasp the rope with a neutral grip (palms facing each other) and pull it over your head so your hands are behind your neck.
- Position your knees far enough back so your torso is angled forward, creating a deep stretch in the triceps.
How to do it
- Exhale as you extend your arms forward by straightening your elbows, pushing the rope ends away from the bench.
- At the peak of the movement, pull the ends of the rope apart to maximize the contraction in the triceps.
- Inhale and slowly bend your elbows to return the rope behind your head, maintaining tension throughout the eccentric phase.
- Follow a controlled tempo, such as 2 seconds for the extension and 3 seconds for the return.
Form checklist
- Keep your elbows fixed in place on the bench; do not let them flare out or slide.
- Maintain a neutral spine and engaged core to prevent excessive arching of the lower back.
- Ensure the movement occurs exclusively at the elbow joint, keeping the shoulders stable.
- Avoid using your body weight to 'rock' the weight forward; keep your torso still.
Pro tips
- Focus on the deep stretch at the bottom of the rep to fully recruit the long head of the triceps.
- Imagine pushing your pinky fingers toward the wall in front of you to enhance the peak contraction.
- Keep your head tucked slightly between your upper arms to maintain a safe and neutral cervical spine.
Make it harder
- Add a 2-second isometric hold at full extension while pulling the rope ends apart.
- Implement a slow 4-second eccentric phase to increase time under tension and metabolic stress.
