At my old gym, there was a kid that I nicknamed "Baby Boy," for reasons I'll get to in a second.
He would walk in, head to toe covered in Adidas jogging gear. Pants, jacket, and shirt. Always the same outfit, unless he was like Einstein and had 7 pairs of the same thing? Anyway, shaved head and headphones that you could hear from 10ft away over the gyms stereo! I used to ask my partner who or what song he was listening to, when the guy was at least 10 feet or more away.
For his exercises, he would be doing odd things....said he was training to be a MMA guy, but I never saw any of the regular MMA fighters in that gym acknowledge him let alone fight or talk to him. I saw him do cable crossovers, rev. standing cable laterals, push-ups standing up off a wall (this was his "finisher" I guess), or he would do sprints on a treadmill.
His car was completely covered in Sirius radio stickers. The oddest thing about him, of the many-and the reason he got his nickname- was he used to carry a jar of baby food with him and eat it while training.
He also had a book of Metzner's H.I.T. training....but I never saw him do anything Mike would have suggested. And his volume was far too high for H.I.T.!!!!
