Alright, I'm thinking about buying some bumper plates for the Oly's and especially the deadlifts. As I lift out in my garage when the weight clings the floor it makes me cringe in fear it might break. So I have two basic questions. 1.As long as the regular plate doesn't hit the ground it won't be damaged/damage the bar right? To clarify further if I put on a 45lb bumperplate and a 25lb regular plate the 25 and/or the bar wouldn't be at any risk of damage would they? 2.I was wondering if you could point me in the direction of a good place to purchase bumper plates online.
