First of all im 5'10-11 something like that and before now I had been benching with a thumbs length grip away from where the rough meets the smooth if that makes any sense. I started looking more into powerlifting and lots of powerlifters grips are pretty wide, I guess about ring finger on the rings. So I have started to do this but I can only press 5 pounds more with this grip than I can with close grip(index finger at rough and smooth). Is there something im missing here?
