Muscle Group: Forearms
Cable Behind the Back Wrist Curls develop the flexor muscles of the forearm. The advantage found in using cables is that they provide constant tension to the muscle throughout the entire exercise. I suggest that you take advantage of this, by emphasizing a peak contraction at the top of each repetition!
Back up to a low cable pulley. Bend down, grab the bar and lift it up. I prefer a short bar. You should hold it down at arm’s length behind you, hands shoulder width apart, palms facing behind you.
Keeping your arms stable, open your fingers and let the bar roll down out of your palms. Close your fingers, roll the bar back up into your hands, and then lift it up and back behind you as much as you can, flexing your forearms.
Concentrate so that only your wrist moves in this exercise.
