I guess that is where my own bias comes through... I have no interest in competing in any way (steroid free or not). Athletic competitions yes, but bodybuilding competitions just seem like beauty pageants on steroids (pun intended), with rampant narcissim abound. It's all about fluff and no function. I don't consider bodybuilders to even be athletes since they are not doing a sport. They are just flexing.
It also seems a little gay (not that there's anything wrong with that). You shave every inch of your body, slather down with body paint and shiney oil, and wear a little banana hammock while you pose for screaming fans. Guess I'm just getting too old to appreciate it anymore. At Coleman's age, I think he's just got to ride the wave while he can since you can't do this forever. Poor guy is still locked in the 80's though.
I admit that I had interest in it back in the 80's (showing my age here). I did do a campus contest put on the a sorority called "Greek God" (and won to for what it's worth), but at 20 I was also obsessed with myself. The person I am now would have not had much interest in the person I was back then. I suppose that is just an expected side-effect of maturing (ideally).
Interestingly enough, if you train for sport or function, you still build a great and admirable body as a side-effect. Putting form ahead of function (to me) is putting the cart before the horse.
Mind you, these are just my opinions. Don't want to knock someone interested in trying one. I'm just rambling at this point. Back to work!
