Dumbbell Finger Curl

This drills the part of grip most exercises skip: the closing action of the fingers themselves. Letting the dumbbell roll to the fingertips and gripping it back trains crush strength useful for deadlifts, carries and pull-ups. Keep the load light and the reps high, since the small hand muscles respond to volume.

How to do it

  1. 1

    Sit and rest your forearms on your thighs with the wrists just past the knees, palms up.

  2. 2

    Hold a light dumbbell in each hand and open the fingers so the weight rolls down to the fingertips.

  3. 3

    Curl the fingers to draw the dumbbell back into a full-palm grip.

  4. 4

    Squeeze hard at the top for a moment.

  5. 5

    Open the hand slowly to let it roll back out under control.

  6. 6

    Keep the wrist itself neutral and let only the fingers move.

Tips

  • Control the roll-out; dropping the weight into the fingers strains the tendons.
  • Keep the wrist from curling so the fingers, not the forearm flexors, do the work.
  • Use a load light enough to complete high reps with a full squeeze on each.

Variations

Common mistakes

  • A thick-handled dumbbell stops the fingers closing all the way, so the crush half of the rep never happens. Pick a pair with a normal handle even if that means going lighter.
  • The dumbbell rolls out at an angle and one end drops first, which twists the wrist as the hand closes. Keep the handle square across the fingers so both ends move together.
  • The hand grips hard from the first rep and never fully opens, turning the set into one long squeeze. The fingers have to open until the handle sits on the top pads before each close.
  • Squeezing at the top is where this earns its keep, and it is the first thing to disappear once the forearms burn. When you cannot hold the squeeze for a beat, the set is done.

Frequently asked

How many reps and how much weight for the dumbbell finger curl?
Sets of 20 to 25 with a light pair, two or three of them, at the end of a session. Small hand muscles respond to volume, so the measure is not the weight but whether every rep finishes with the handle pulled into the palm. Add reps until 25 is easy on all sets, then move up one dumbbell size and drop back to 20. The loads are tiny enough that two or three sessions a week take nothing away from the rest of your training.
What can I use instead of dumbbells for the finger curl?
A barbell across both thighs trains the same roll with both hands at once and takes smaller weight jumps. A hand gripper or a tennis ball squeezed for reps covers the closing action anywhere, though neither gives you the roll out to the fingertips. A filled bottle or a small kettlebell held by the handle works at home. If you own a plate, pinching it by the rim for time is a different but useful way to load the same fingers.
Who should be doing dumbbell finger curls?
Anyone whose hands open before their back gives up on heavy rows, deadlifts or carries, along with climbers and grapplers who have to hold on. Doing it one hand at a time also stops a stronger hand covering for a weaker one, which is the main reason to pick dumbbells over a bar here. It is a poor use of time if you want visible forearm size, since the loads stay small, and worth easing off if the fingers or the inside of the elbow stay sore between sessions rather than pushing the reps higher.
