arms, nice gains......for chest, try this (solid advice)
try working chest for two weeks on this program:
do three or four good warmup sets on either smith incline, or reg incline, whichever you feel targets your upper chest most directly, doing weight that you could probably lift 25 times if you had to, but just do 10 15. you don't want to stain yet. then comes the real set, do just one, balls to the wall superset (I do mine on smith cause like clubber lang, I train alone, I live alone, I fight alone...but that's another story), also because it's easier to set up a superset on smith. On this superset, put on weight that you could max do for 5 or 6, but also keeping in mind that you'll have to remove some plates, or plate to continue. for your size you might want to have however many plates and a quarter (to remove for superset) and then continue for however many more. make sure your not doing weight that forces you to wiggle around for those last reps, this method is about pain, not strength. then, when your done with that one puke inducing set, stretch the fuck out of your pecs CAREFULLY THOUGH, as much as you can. the rest is downhill, roughly 3 to 6 shaping/stretching sets after this and your done. example: cable crossovers and incline dumbells. repeat this ever seven days, or whenever you feel your definitely well rested. write if this doesn't work, I will be suprised. peace.
