So I have been training 3 weeks, been to 8 classes so far. In my last class I bruised my sternum, and had to sit out of the last few rolls it hurt so bad. I skipped class on Wednesday, because it still hurt, and I would love to go to class tomorrow, but it still really hurts. So I am wondering if I am better off going to class and just drilling technique? But pushups and such hurt also, I don't want to be a distraction or a bad training partner. So should I just wait it out, even though I am just getting started, or push through and train around it?
