Dumbbell Isometric Wrist Flexion Over Bench

Muscles worked

Setup

1. Kneel beside a flat bench and rest your forearm on the bench with your palm facing upward.
2. Position your wrist just past the edge of the bench so the hand is unsupported while the forearm remains flat.
3. Grasp the dumbbell and use your opposite hand to help lift the weight into a slightly flexed (curled) position.
4. Ensure your elbow and forearm are firmly planted to isolate the wrist.

How to do it

1. Hold the dumbbell in a static, slightly flexed position, keeping the wrist completely rigid.
2. Maintain a steady, deep breathing pattern while bracing your core for stability.
3. Hold the contraction for the target duration, focusing on keeping the weight perfectly still.
4. After the hold, use your non-working hand to safely lower the weight before switching sides.

Form checklist

• Keep the forearm glued to the bench to prevent shoulder or elbow compensation.
• Do not let the wrist drop into extension (bending backward) during the hold.
• Maintain a firm, active grip on the dumbbell handle throughout the set.
• Keep your shoulders level and avoid leaning your body weight into the working arm.

Pro tips

• Squeeze the dumbbell handle as hard as possible to maximize muscle fiber recruitment through irradiation.
• Focus on the mind-muscle connection by visualizing the muscles on the underside of your forearm shortening.

Make it harder

• Increase the duration of the hold or the weight of the dumbbell.
• Use a thick-grip implement or wrap a towel around the dumbbell handle to further challenge the grip.
