Ok, yesterday was the first time I tried DL'ing with a belt, and I goddamn hated it. I did my warmup 135x8, then 315x5 with the belt like normal, the for my first 'heavy' set which was supposed to be 365x5 I put the belt on. I have a fairly decent quality new Harbringer belt that works great for me for squats, so I'm discouting the possibility that it's my belt. So anyways, I go to do the first rep of my set, and the belt first slowed my lift down mad, second really hurt my stomach. I didn't want to try a second rep, it was too weak and painful of a first rep. So I put the belt away and did my 395x3, 415x2. I was fucking pissed off though, cuz that damn belt ruined a whole friggin set for me. So the Question is, why did the belt fuck me up? Am I missing something?
