Cont: He is a BIG name in numerous communities, not just body building. He bridges the gap between hardcore body builders and the rest of us; a better choice than any current bodybuilder name out there IMO..
What Arnold has been is more than most anyone in the bodybuilding community. He is an EXTREMELY good partner to have on this venture. All due respect, it is telling that you could not include an alternate name for them to choose, rather than Arnold. He is THE name.
He's still the most respected and known man in the body building community though. Everyone knows Arnold. My mother who has never lifted a day in her life knows Arnold. I think it was an ingenious move.
