Do any of you dweebs do this?

I know a few folk that do and they all reek of scientology-esque fervour.

Is it any good? I am put off by the skipping and the fact that 'Crossfit' is seen as a competitive sport in its own right now. But wait guys: it's not just a 'sport'- it's also a Philosophy. Why does this piss me off so much? How is it really that different from my beloved yoga, which is also all about the state of mind?

Maybe it's the silly acronyms.

Anyway, what does the hivemind say?
