Can you get an MMA trial? Seems like about 80-90% of people that start training in MMA (at least our gym) quit very quickly. It's not for everyone. It would suck to waste your money if it's not for you.
I think that MMA would get you in better shape, but I've never done cross fit so I can't really say. MMA is a lot more exciting than just working out though, for sure.
Yeah, I can get a trial. I'm down for it though. I've been an athlete all my life playing different sports, mainly football and track & field, but I've been out of practice for a couple of years with just working out and being active, generally speaking. MMA is one of the only options that truly interest me at this point.
