So I get a pain in my chest during preacher curls, usually after I'm done working out, its like deep in the pit of my chest, I'm guessing this has something to do with my diaphragm and breathing? I at least think I'm doing a good enough job breathing in and out. Anyone else have this problem and or useful advice?
