A former hockey player and skateboarder, Jason Crandell has had his fair share of falls. Which is why the Ohio native isn’t afraid to challenge yogis in arm balances and inversions that take practice and patience. (Just ask him about the 20-minute headstands he was asked to do during his teacher training with Rodney Yee.) Though the longtime Yoga Journal contributing editor is based in San Francisco, he spends much of his work life leading teacher trainings of his own and workshops in Asia and Europe. Otherwise, catch him in any of his Yoga Journal DVDs, including the Complete Beginner’s Guide.
