Oh, yoga: the pasttime of hippies and stressed-out soccer moms alike, that blissed-out exercise of Hindu philosophers. It has no demographic, and so it bears no judgement. There's just something so delightfully zen about it (and yes, I realize that I'm mixing Eastern religions here). It's, like, 30 percent breathing, after all. I can get down with any workout regimen that includes something called "heart opening exercises." And it's a great time to get into yoga here in Milwaukee.
