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.
