Cable Reverse One-Arm Curl

The reverse curl one arm at a time with a single handle on the low pulley; each arm works alone against the cable.

How to do it

Setup

Facing the low pulley, a single handle held overhand, working arm long, elbow at the side.

Steps

Curl the handle up, the back of the hand facing up.
Stop when the forearm is vertical.
Finish the reps on one arm, then the other.

Common mistakes

Torso twisting toward the working arm: square the shoulders to the stack. Shoulder of the working arm hitching up: keep it down and back. Curling across the body: the handle travels straight up in front of the shoulder.

Breathing

Exhale on the curl, inhale lowering.
