i stopped touching years ago and FINALLY the pain went away. i read an article before i decided to stop touching that said when you get close to touching your chest your pecs stop expanding and its your shoulders that roll back which makes you able to touch. when your shoulders roll back it is a very unnatural movement that will cause injuries especially with heavy weight. take notice of what your shoulders do when the bar goes from about 2 inches from your chest to touching your chest. when powerlifters use heavy weights they use a bench shirt which gives maximum support when touching your chest thus avoiding shoulder injuries. most powerlifters use a shirt most of the time even when training when they get to there heaviest weights. now for those powerlifters reading this who are gonna say "i dont use a shirt when training only in a meet", remember i said most lifters NOT ALL lifters. anyway, for me, i would much rather stop about 1-2 inches from my chest and avoid injuries than be immune to on lookers saying 'he didnt touch his chest so that doesnt really count'. plus, give it a try, and im sure you will find that it mat be harder to have to completely stop 1-2 inches from touching than having the momentum of touch and go benches. just my 2 cc's.............
