(I tried posting this to /fit but I don't have enough karma)

Hi, I've had this problem for a while. Been working out for six years now but I honestly can never say that I have ever gotten chest strain post-workout, any sort of pump or even doms. I am extremely confused.

I have tried chest flies, military presses, bench presses, push ups, weighted push ups, and all the assorted chest exercises I've been able to find on the net. I've tried high weight (things I can barely lift), low weight(things I can lift for 12 reps), all the weights in between, 6,8,10,12 reps, 4,6,8 sets in various permutations.

Yet none have ever triggered chest soreness. I do not have this problem with other muscle groups (my back, abs, legs and other muscle groups experience soreness when I work them out hard) but I can never seem to work my chest out even when I work out to failure and beyond, and it never seems to grow. Often I find other muscle groups like my shoulders or arms feeling sore post workout, but no matter how hard I try to isolate the chest (and not use anything else) it never responds.

Help?
