If you dont have forearms like Popeye, give this wrist roller a try and start working those lower limbs, making them an offer they cant refuse: fall off or grow bigger and stronger. The Wicked Wrist Roller trains your grip, wrist and forearm in a flexion/extension movement, like when doing wrist curls (regular and reverse). It is designed so that you train both concentrically (winding up the cord) and eccentrically (allowing it to unwind under control). Made of 2" diameter knurled high-strength steel, it can be used in free-standing mode or on a 1" or 1-1/16" bar, where its slick bushing system gives it a smooth ride. Comes with an 10-ft., 1,000-lb. test rope and a small carabiner; add a loading pin (not included) for easy weight changes.
