Went to the CrossFit gym today. Nice group of trainers and members. I liked everyone's attitude. Oh and my ass was thoroughly kicked by a workout that I should be able to do, as in I couldn't even finish it because I got so lightheaded. Trainer was encouraging and knew when to just call it off. Going back Monday for the next initial session (they have 6 initial sessions that you have to do before joining the regular classes). The classes themselves are limited to a max of 12 people (you sign up ahead of time).
I was a little worried about driving home afterwards. I waited until I was no longer getting lightheaded but I was still a little slow mentally. Kinda like when you are really tired, you see everything but you are slower to respond. Luckily it is only like 3 minutes home and nothing unexpected happened.
