Cable Standing One Arm Triceps Extension
Cable Standing One Arm Triceps Extension Exercise Description
The Cable Standing One Arm Triceps Extension trains elbow extension with a constant, guided resistance from the cable stack. It primarily targets the triceps brachii (long, lateral, and medial heads), while requiring the shoulder girdle and trunk to stabilize the arm and torso. Standing unilaterally lets you focus on keeping the upper arm close to the torso and the wrist neutral, encouraging clean mechanics without momentum. The cable’s continuous line of pull promotes smooth force across the range of motion and helps maintain tension during both the extension and controlled return. Maintain a neutral spine, set the scapulae (down and slightly back), and minimize shoulder movement so the triceps do the work.

How To Do The Cable Standing One Arm Triceps Extension Exercise
‘- Set a high pulley and attach a single handle.
– Stand facing the machine; adopt a stable stance (feet hip-width or a slight split stance).
– Grip the handle with one hand; keep the wrist neutral.
– Tuck your working elbow close to your side with the upper arm vertical; set shoulders down and slightly back.
– Brace your trunk; keep a neutral spine and level ribs.
– Start with the elbow flexed (about 90 degrees), forearm in line with the cable.
– Extend the elbow by pressing the handle down until the arm is straight without locking hard; keep the upper arm still.
– Avoid shrugging, flaring the elbow, or letting the shoulder drift forward.
– Control the return, allowing the elbow to flex back to the start under tension.
– Keep your head neutral and torso quiet—no leaning or swinging.
– Switch arms and repeat with the same setup and control.
Cable Standing One Arm Triceps Extension Tips
‘- Stand facing the machine with a stable stance (feet hip-width or a slight split stance).
– Grip the handle with a neutral wrist to promote clean mechanics.
– Tuck your working elbow close to your side and keep the upper arm vertical.
– Set your shoulders down and slightly back before you start and maintain that position.
– Brace your trunk and keep a neutral spine with level ribs to keep the torso steady.
– Begin with the elbow flexed to about 90 degrees, forearm in line with the cable.
– Extend the elbow to press the handle down until the arm is straight without locking hard.
– Keep the upper arm still; avoid shrugging, flaring the elbow, or letting the shoulder drift forward.
– Control the return so the elbow flexes back under tension rather than letting the weight pull you.
– Keep your head neutral and your torso quiet—no leaning or swinging.
Cable Standing One Arm Triceps Extension Beginner Introduction
The Cable Standing One Arm Triceps Extension is a cable-based isolation movement for training the back of the upper arm. Using a single handle on a high cable, it emphasizes straightening the elbow against steady resistance, while the standing position brings the shoulders and core into play for support. Because only one side works at a time, attention shifts to how the working arm moves in relation to the body, rather than generating power with the whole torso.
During the exercise, the lifter stands facing the machine in a solid stance and holds the handle with one hand. The upper arm stays close to the side, the wrist lines up with the forearm, and the elbow bends and straightens as the cable resists both the downward press and the return. The cable’s smooth pull encourages a controlled tempo instead of jerking or swinging. The theme of the movement is steady posture, relaxed but stable shoulders, and precise elbow motion so the triceps handle most of the effort.
