Starting Position
Grab a barbell using a pronated grip (palms facing down) and sit down on the end of a flat bench. Rest your lower arms on the top of your thighs or on the end of the bench so that your wrists are just off the end of your knees or of the bench.
Execution
Without moving the forearms, slowly raise your hands up as far as possible squeezing the forearms at the top of the movement. Pause, and then slowly lower the barbell back to the starting position. Repeat for desired reps.
