Hence the reason that you just now scared me to where I will never do incline flys , unless its on a machine.
But Im not a big fan of them , but I tried them like a week or two ago when I could go to the gym , I did 45's on dumbell pullups , feet on ground , back on a bench seat , They really gave my chest bones/ ribcage a stress feeling like if I went really heavy it would break open my rib cage.
I read somewhere that pullovers were good for rib cage growth so that was the reason I asked.
If I incorporate them to my routine I will probably use them as a finishing exercise for the muscle groups , Which what muscle group do you recommend I throw em in for.
