Hi, so far for DownDog just the facebook group but im also in a couple Yoga and Meditsation facebook groups, one that I would recommend is ‘Hypermobile yogis’. It is targeted for people wanting to use yoga to help their hypermobility, but it is so good at understanding the anatomy of yoga that even for people without hypermobility I would encourage to follow. Hope that helps. Glad to see other DownDog yoga fans out there !
