Uh oh. Have you gotten started on your Sirsasana Challenge yet? Looks like the kids at YogaLocal NYC are way ahead of you! In an effort to be goofy, and to sell their new iPhone app, the YogaLocal team have pulled a Cora Wen, yogaing through the likes of Grand Central Station and sirsa-ing up a subway escalator! (cool, but ick, btw). And how do you like the clever (hopefully legal) use of John Lennon’s “Oh Yoko”? Attention-grabbing? Yessiree, even for focused yogis. We’re willing to bet their marketing force put in some overtime at viral interwebs 101. Know how we know? Those youtube tags start out with the innocently usual suspects: “yoga” “headstand” “NYC” which are then closely followed by “sex” “boobs” and “doggystyle”. Hot. Still, if you straphangers are strapped for a yoga class it looks like a pretty cool and useful app.
