Chest that’s where a Slin pin comes in handy ... LOL... never hit the chest, but I’d be thinking about 5/16
I’d say as long as ur not Jared before he went on the subway diet— 1” for chest is over kill
I use 5/8 26gauge for delts, and noticed no more bruising as compared to 1”
My argument was with glutes and quads. Never even considered going shorter than an inch for anything until I saw all of you guys recommending slin pins. I was going to do delts but I cant reach my shoulder so there is no way unless I get someone else to do it. And I dont want to rely on someone else for my shots. So figured I'd give upper chest a try and with a 25g 1inch there is no pain. Just curious what people use for their chest.
