First off I have to say I'm a beginner so there is a good chance my form is horribly wrong. For chest exercises today I was doing 5 sets of 12 reps on incline, flat, decline, and butterflys on a flat bench. I also did barbell standing arm curls and hammer curls.
Normally when I get home after a workout, my chest feels good and I can tell I've worked it. Tonight my arms are incredibly sore but my chest doesn't feel any tighter or sore like it normally does.
Any suggestions on what I may have been doing wrong?
