How to do it

  1. Sit on a bench with your forearm flat on the top, palm facing down, and your wrist hanging just past the edge.
  2. Hold a light dumbbell and let your wrist drop fully so the weight pulls your hand down toward the floor.
  3. Lift the dumbbell by extending your wrist upward, keeping your forearm completely still on the bench.
  4. Squeeze the top of the forearm at peak contraction with the back of your hand pulled toward your forearm.
  5. Lower the dumbbell back down slowly over 2 to 3 seconds, fighting the weight on the way down.
  6. Repeat for 12 to 15 reps, then switch arms and match the rep count on the other side.

Common mistakes

  • Picking a weight too heavy, which forces you to use the elbow or shoulder to swing the dumbbell up.
  • Lifting only a few inches at the top instead of working through the full wrist range.
  • Letting the forearm drift up off the bench, which removes the isolation entirely.
  • Rushing the lowering phase, where most of the forearm extensor strength is built.
