Your best bet would be LA Fitness, to be honest. I used to train at Bally off Powers and Colonial. But, they closed it. It was "hardcore", in the sense that there were plenty of big dudes, mostly black (and many of them Haitian), two legitimate power cages and plenty of free weights.
LA Fitness has plenty of toys, including dumbbells that go up to 150 lbs. But, the chrome is so shiny you can see your reflection. The plates are all rubber-coated and jet black. But, there are scores of them, more than enough for you to get down and act a fool.
