Reebok on the Rebound?

So I’ve been offline for a few days and I come down off the slopes from boarding in the Tahoe area to an email from a blog fan (you know who you are!) with a few links to Reebok’s new ad campaign and product line. Please click on these links, but the short story on the marketing tag line for Reebok’s new EasyTone sneakers is “better legs and a better butt with every step”. What? 

According to Reebok, American sales rose 4 percent—its largest increase in four years—on the strength of that launch and the goal of the campaign was to get consumers to “reethink” their perceptions of sports “and remember why they play, sweat and cheer—because it’s fun.” I find this statistic a bit troubling.

My question is this—if Reebok’s target market is women who want to buy ‘performance gear’, how does this commerical appeal to women? With this ad, who are they really trying to get to “rethink their perceptions of [women’s] sports”?
