Manus Grip, Advanced Thick-Bar Adapter
Two Sizes:(1). Original Manus Grips: 2 inch thick in diameter(2). Manus Grip PRO: 2.5 inch thick in diameter.Made of very heavy-duty silicon rubber, Manus Grips turns any barbell or dumbbell into a super-thick bar. The extra thickness makes the weight harder for you to grip, forcing you to activate muscles you wouldn't normally use on a thinner bar. This will lead to a STRONGER grip, STRONGER forearms and a STRONGER upper body.Designed by one of the best product designers in South Korea, Manus Grips are being used by professional armwrestlers, gripsters, powerlifters, MMA fighters, and members of the Seoul Metropolitan Police Agency!Design patent pending.
