BISTAR DUMBBELLS PAIR 55 LB
Bistar triangular design dumbbells.
-Put your hand inside and then there is that little bar that rests against the wrist.
-The original intention they had was for the front of the wrist to bump the pad as the dumbell was lifted, thereby forcing the weight outward and increasing the load. Sort of like a cam does, but turning the weight around and putting the pad on the front of the forearm frees up almost all the gripping needed. .
