Not sure if you can help me out at all on this problem since we are built completely different, but with my deadlift. I am having a bit of a problem getting a good grip with my left hand, because of the size of my gut (which i am working on daily, and I know that is not a problem you have) and the shortness of my arms, i seem to have to lift sumo style, but becuase of this i can't seem to keep my thumb around the bar and have to just use a thumbless grip, Any suggestions on how i should be working on this other than the obvious ab and cardio work (which I am doing daily) ?
