I think that in the '70s bodybuilders attained the perfect combination of mass and conditioning. The cadaver look of Munzer was not only unhealthy but looked hideously ridiculous. Things got worse when mAss monsters came along. Big guts and big butts are turn-ons for schmoes alone.
Many of Mentzer's photos display perfection in both mass and aesthetics, just as Arnold's, Zane's and Padilla's did in their own way. "Maesthtetics" anyone?
