CROSSFIT I keep hearing about it, and suppose to be the greatest thing since sliced bread. I have never heard anything about it, maybe being in the close knit powerlifter trib I am in, we dont pay attention to these new, all the rage "fit" routines. But well at Recruit training I heard this is what the Marine Corps is going to. Also from what I hear this is what SF use, dont know how true that is, just something i have heard. ANyone know anything about this, or have you used it?
