Lululemon is not just a fancy place to buy yoga pants; it’s a hub of wellness activism. Each store prides itself on getting out into the community and finding out how best to bring its mission of inspired, active living to the people. It’s kind of like a cult. A really, really healthy cult with a killer butt. One of the ways it woos new believers is with free weekly yoga classes in its store (all levels welcome, mats provided), as well as occasional free classes at other fitness studios around the city.
