Grasp a dumbbell using an underhand grip (palms facing up) and kneel down in front of a flat bench.

Rest the back of your forearmon top of the bench so that thewristholding the dumbbell isjust off the end of it.

Bending only at the wrist, let the dumbbell drop as far as possible. You can rest your non-working arm on the bench for stability. This is the starting position for the exercise.

Slowly raise the dumbbell up as far as possible squeezing the forearm muscles at the top of the movement.

Pause, and then slowly lower the weight back to the starting position.

Repeat for desired reps.

Exercise Tips:

A light weight should be used with proper technique. It doesn't take heavy weight to make this exercise effective.

Keep the rep timing slow, and pause/squeeze the forearms for a count of two at the top of the movement for added intensity.

Use a full range of motion by allowing the weight to drop as far as possible at the bottom of the movement.
