Hey, can anyone tell me why some pro bodybuilders prefer to lift with their thumb behind the bar rather than have a grip around the bar? I saw a picture of Arnold doing 400+ lbs bench press with that type of grip, and it just looks dangerous at a glance.
I'm currently experimenting with grip types, after discovering that my current grip is not the best, as there is a lot of stress on my wrists. It's a little frustrating, because the new grips are awkward and I have to decrease my bench/shoulder press weight.
Any help would be great.
