Crazy or brilliant?

I don't know which I am - crazy or brilliant - but I just signed up for a fitness bootcamp. It starts July 27th. A girl I work with does it and suggested it. Sounds like fun, but it's at 6:30pm on Monday/Tuesday/Thursday, so I could very well die. I'll be kicking my own butt at the gym in the coming week to prepare my body, although I'm sure a kickboxing class won't come close to the intensity I'll be experiencing at bootcamp. I'm on my way to losing the (at least) 10 pounds I want to drop before the wedding and gaining toner arms. Wish me luck!!
