I used to switch my grips ALL the time...
now I just do the ring on the ring.... thats what i was doing when I was at my peak.
There more of a satisfaction feeling when I go closer than that because I can feel my triceps actually working , I barely feel them working unless I do higher reps. When I do the ring on ring grip..
But im sold on the fact that its better for me to do wider than closer since I think its better to focus more on chest and shoulders than triceps with bench.. There always great exercises like dips...
I tried reverse grip , I was pretty decently strong at it compared to my other lifts.. maybe 10-20% less than my normal maxes , thats also being fairly new at trying it out but.... I just heard do much against it for injuries and safety , true or not I dont care because its more tricep specific anyway.
