Can anyone confirm that the plates at the Olympic lift stations are true bumper plates, and if so, is intentional dropping allowed OK in the gym policy, for example, after a power clean?

Indeed, people do it often. But best is to ask the tall bold guy that works there. Hi gives weight training.

The best shot would be asking either a receptionist or a trainer. But I feel positive about your question. A lot of people dropping weights.

Yes they have the bumper plates and as long as your in the Olympic lift station it's fine to drop the weights

I don't know but people seem to be doing it
