Crossfit vs p90x vs Kettlebells

A conversation recently came up over at twitfitter on the relative differences of Crossfit and other newish intensity based fitness programs (like p90x and kettlebells) and whether or not fitness programs like Crossfit will take over the globo gym and behind the back wrist curls will become a thing of the past or perhaps they’re just a fad.

I took the position of Crossfit being superior to the others and took a quick jab at curls in general being an inefficient exercise.

I thought the conversation was pretty good.  See for yourself over at twitfitter, here.
