I'm all for yoga with horse and Yoga on horse back! For one it's amazing for your horse keeping them stretched and flexible but it's a great way to connect on a deeper level with your horse! My older sister also my partner in crime lol loves yoga and someday would like to teach while my obsession is with horses and we have talked more than once about combining them!
Is it yoga to improve your horseriding, or actual yoga on a horse? Because I would say yes to the first, but a harsh no on the second, I don't trust my horses enough to stand still while I do some weird pose on its back 😂
