I was lifting 265lbs on DLs and I was scraping the **** out of my shins. At the end, I felt I could do more. So I threw on some more weight the following week so I was doing 280lbs. On the way down, the bar starts rubbing up against my quads which never happens. Is this because of bad form or too much weight causing bad form? Also, at 265 I can hit the floor but at 280 on the way down there's a lot of pain in my knee. If I hit the floor I wouldn't be coming back up, so I don't. I stop right around my shins.
My guess is that there's too much weight and that my form is fooked. Any other ideas?
