Crossfit?>>Am I crazy or what???

So I slacked major this winter. I lost my everday workout buddy due to a move and with it my motivation. But by summer I want to hike major elevation so I decided to get back in gear. I thought I will hit the gym hard and then prepare myself to join a crossfit gym.

But then I thought thats just procrastinating more. I have been hanging onto this last fifty pounds for too long. So I did two things. To break through my current plateau of ten pounds I deactivated my facebook page till I loose it. Then I decided to join a crossfit gym now! I meet with the two near my work this week and decide on one then start the next week. OMG I may be crazy. It looks so intense. Has anyone done it? Anyone over 50 lbs overweight done it?

I know I can do it and I am excited. So excited. But I am scared too! Petrified. Will let you know how it goes.
