Wrist Curl
Forearms stay down, only the wrists move. The wrist curl lets the weight roll back into the palm and then flexes the wrist up, which is the direct work that stops your grip failing before your back does. Lifting the forearms off the thighs to help is the fault. Short high-rep sets a few times a week do more here than heavy singles.
Setup
- Seated, forearms resting on the thighs, hands past the knees, palms up.
- Let the weight roll to the fingertips.
How To Do It
- Curl the weight back into the palm, then flex the wrist up.
- Squeeze at the top.
- Lower slowly, letting it roll back to the fingers.
Breathing
Exhale on the curl.
Common Mistakes
- Lifting the forearms off the thighs to help.
- Going heavy. The wrist is a small joint and does not need it.
Programming It
Two to three sets of 15-25. High reps, short rest.
Why This Exercise Works
The forearm flexors are small, high-endurance muscles, which is why they respond to high reps and short rest rather than heavy sets. Training them directly is the difference between a deadlift that ends because your back is tired and one that ends because your hands opened.
Where You Should Feel It
The forearms, burning within fifteen reps. Rolling the bar to the fingertips at the bottom adds the range that makes it worthwhile.
Where It Fits in a Program
Small muscle, high reps, and the reason your grip stops failing before your back does. Save it for the back half of a session, where fatigue costs you little.
Progressing and Regressing It
To progress the wrist curl: add a small increment or extend the set with a partial burnout. To regress it: reduce the load and roll the bar to the fingertips for range.
Who It's For
Anyone whose grip fails before their back on rows and deadlifts. Short, high-rep sets several times a week work better than heavy ones.

Do I need dumbbells or a barbell to do this?

Is this safe if I have an existing injury?
Elbows and wrists take the brunt of the wrist curl, and both are slow to settle once irritated. If the ache lingers into the next day, reduce the load or change the grip angle before you train it again. Not medical advice.
