Boot Camp?

So, my gym offers boot camp classes. Have any of you guys taken these? I haven't. They scare the crap out of me. My super fit, gorgeous, thin, gym-workin', zumba-teachin' soon-to-be Sister in Law took a boot camp class and was sore for like, a week.

I'm just terrified to be yelled at and have to run around a big obstacle course in the pouring rain. Plus, I would have to buy some tactical pants.



Anyone have any experience with a boot camp class? I'd love to hear it.
