get everything out of the gym in order and then focus on your business inside the gym, even if you have a bad chin/punch taking ability, well you are at least finding it out early and can work around it, it means you will have to work even more on defense and movement, slip shots and don't take them to the head, turn your opponent, cover up take power out of shots, unless you're at a fatal or long term risk you shouldn't really give up so quick
