i’d ask your doctor whether or not you’re a-ok for yoga first. then i’d look for beginner level or resorative yoga classes. call a studio in your area and ask for recommendations for classes/instructors based on your specific injury. most good teachers ask students at the beginning of class if anyone has any injuries or limitations. if they don’t- tell them your injuries so they can help you modify or avoid certain poses. good luck- yoga has done wonders for my lower back issues!
