Yes, women really care about biceps peak.
I think it's limited to mostly college age/high school girls still in the club and party stage. At that age the vast majority isn't making big money so looks counts more. It's kind of a status symbol for a young girl to have a jacked by her side. After that it's a big wallet. Sure being in shape and having some muscles is always a plus, but it's a distant second to money, power, success -- all interrfelated.
BTW, this guy reminds me of Halo.
