Hate the rubber dumbells and plates/....
theres a ballys in glendale, ca. that uses 7.5lbs steel plates on dumbells instead of the conventional 10lb plates
so for example a normal 85lb would have 4 -10lb plates on each side
this gym it has its 85lb dumbell with 5 -7.5lb on each side and a 2.5 on each side... make it appear your are stronger then you really are
