I’ve gotten most of my yoga instructions from Wii fit lmao. But there’s a YouTuber that does workouts that I’ve liked, she seems to do yoga too https://m.youtube.com/@Heatherrobertsoncom/search?query=Yoga Rule of thumb is, if something hurts in your joints rather than in your muscles or tendons, you’re doing it wrong. I think the injury risk for yoga is pretty low though.
