Sorry to mislead anyone, they are 33lb plates. They gym only has 8 x 20lb plates so I use the 33lb ones. I wasnt trying to scam anyone. I call that 520lb. I never said it was more. It just looked cool to me. ONce again, I wasnt trying to mislead, I just logged on and saw that people think it was 675lb. I have posted in other places saying it was 500+. I know everyone else could do it easy, it is just a good lift for me.
