How to do it

Single-arm triceps extension with a cable and the palm facing up, which demands a stable elbow through the whole range.

Form. Line up the cable, keep your elbow beside your body and extend without turning the shoulder or losing your wrist position.

Common mistake. Flaring the elbow, using your body to push, bending the wrist, or moving the shoulder instead of the elbow.
