I did Crossfit for about 6 months - it was grueling but fantastic. I'm back to cycling 12 weeks of powerlifting with 12 weeks of kettlebells.

Crossfit isn't for everyone. Like That guy said, it's very popular with police and military, people looking for a really high standard of very practical fitness.

If your goals are to fit into those size 38 pants or not get winded running up a flight of stairs, steer clear of crossfit.

If you're going to do Crossfit you need to be incredibly dedicated and motivated. Your typical gym rat who does a few sets of benchpress and calls it a day will be smoked after a Crossfit workout. Only the particularly dedicated make it through for any significant amount of time.

I would highly recommend it if it fits your goals, but your goals should be to attain a pretty high level of physical fitness and general athleticism. This isn't a "lose 10 pounds by Christmas" kind of program.
