I like "Yoga with Adrienne". She makes 30 day series and they get increasingly difficult with each day.
Ive yet to complete one through, but the furthest I've gotten is like day 22 I wanna say. Yoga's great tbh and I should do more of it. For me, it helps provide awareness of my physical state which makes assessing my mental state a lot easier. An ex of mine had told me they did some pose before and it caused her to see colors somehow...weird, I've never had that happen.
Sounds a bit woosah to me, but even just the physical effects of yoga alone are amazing.
