Cable Wrist Curl

The seated palms-up wrist curl with the bar of a low pulley; the cable keeps tension on the flexors through the whole arc.

How to do it

Setup

Seated at a low pulley, forearms resting on the thighs, palms up around the bar, wrists past the knees.

Steps

Open the fingers and let the bar roll toward their tips.
Wrap the fingers back around and lift with the wrists.
Lower slowly while the cable pulls forward.

Common mistakes

Leaning back to haul the stack: the torso stays still; lighten it. Stopping before the fingers open: let the bar roll out every rep. Forearms sliding off the knees: set them back before the next rep.

Breathing

Exhale on the curl, inhale lowering.
