Cable Alternate Triceps Extension

The one-arm overhead extension from a low pulley with the free hand bracing the working elbow; the arms take turns.

How to do it

Setup

Back to a low pulley, one handle held behind the head, elbow up, the free hand across the chest holding the working elbow.

Steps

Straighten the arm to press the handle overhead.
Let the free hand keep the elbow from drifting.
Lower the handle behind the head, then work the other arm the same way.

Common mistakes

Pushing the elbow up with the free hand: it only steadies it. Leaning back to finish: stand tall, ribs down. Dropping the handle behind the head: lower it slowly.

Breathing

Inhale lowering, exhale extending.
