These are good observations. My back is not a factor in the hesitancy, that has more to do with just trying to sit back and stay tight and not knee slide which hasn't been working great either. I do realize I need to speed them up and arch less - will work on that next week. Agreed on the beltless deads. I think I'm going to try to only use the belt for top sets of 3 or less. I just seem to deteriorate on a set of 5 with it on. Thanks for chiming in!
