How to perform Palms-Down Dumbbell Wrist Curl Over A Bench

  1. Start out by placing two dumbbells on one side of a flat bench.
  2. Kneel down on both of your knees so that your body is facing the flat bench.
  3. Use your arms to grab both of the dumbbells with a pronated grip (palms facing down) and bring them up so that your forearms are resting against the flat bench. Your wrists should be hanging over the edge.
  4. Start out by curling your wrist upwards and exhaling.
  5. Slowly lower your wrists back down to the starting position while inhaling.
  6. Your forearms should be stationary as your wrist is the only movement needed to perform this exercise.

Sets & reps by goal

Form tips

  • Move slowly and let the wrist travel through its full range instead of bouncing at the ends.
  • Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
  • Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
  • Control the lowering phase — a 2–3 second descent builds more than dropping the weight.

Common mistakes

  • Loading so heavy the wrist collapses instead of moving through a clean range.
  • Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
  • Chasing weight jumps before the current load feels solid on every rep.
