Men's Physique division is booming here in California. And yes, you need to train to get in shape for Men's Physique, but not train like a bodybuilder, where muscularity is the most important over physique. However, I do agree with you that the board shorts eventually need to be just regular shorts. However, physique over muscularity in this division, making it completely different than bodybuilding.
Classic bodybuilding I assume was and is supposed to be the competitors that with to have overall symmetry more important than the mass monsters. As we all know, muscularity is what drives the sport of bb lately.
Bikini - well... just awesome! Love it. The Bikini division was made for the Getbiggers! And please - we need more!
