New to yoga? Test it out. Veteran yogi? Try a new class. That’s what DFW’s Free Day of Yoga is good for. Happening September 3, tons of local yoga studios are offering complimentary classes from morning until sundown around the city. See here for a list of all the studios and classes available. You can search by zip code, start time, and class level. RSVP info, if necessary, is provided.
