I saw this at a party about three years ago. It was standing still by the entrance for ages, so I figured it was a robot or even just a model. Once it started moving around and interacting with people, I figured it was a guy in a huge suit.

Poor chap, he must have stood still and done nothing for about two hours before he got to even move around.

Crossfit is the bomb. As a precursor, you might also try the Starting Strength program, from the 2nd edition book of the same name by Mark Rippetoe. That did things to my body composition that I wouldn't have believed possible otherwise.
