open backs are easier on and off but you will most likely need someone to help you get it just right..
first off it is possible to get 200lbs from a shirt HOWEVER do not think that you put it on and voila you go fromma 225 bencher to a 425 bencher overnite..unless youre a natural that is not going to happen..only by practicing in the shirt with proper form will you be able to get the most out of it..dont let anyone else tell you otherwise..
i lift in a reg BB'ing gym so when i put my shirt on or briefs people look at me strange..I find it extremely funny that when i squat people come up to me more and ask me questions about form the box etc..generally they are psoitive and want to learn..However when i put my bench shirt on its the complete opposite my brother overheard a few guys saying how its all the shirt i cant really lift the weight etc..ignore those people..my point is dont be afraid to be different in your gym
