Cable Standing Single-Arm Overhead Triceps Extension

The one-arm overhead extension from a low pulley with a single handle, the free hand tucked behind the back.

How to do it

Setup

Back to a low pulley, a single handle held behind the head, elbow up by the ear, the free hand behind the back.

Steps

Press the handle straight up until the arm locks out.
Hold the upper arm still beside the head.
Lower the handle behind the head slowly; switch arms after the set.

Common mistakes

The upper arm swinging forward: only the forearm moves. Arching back to finish: ribs down, glutes tight. Cutting the stretch short: let the hand reach behind the head each rep.

Breathing

Inhale lowering, exhale extending.
