Because ordinary classes in general yoga clubs are for everyone to practice with a teacher.
If you can't sign up for such a class at all, it's easy to discourage you.
When my muscles relax, I will go to a yoga club.
I don't know where you live, so I can't recommend a yoga club
Anyway, beginners, if they only enroll in ordinary classes, I don't think there is any difference between yoga clubs.
Practice yoga 2-3 times a week.
Before and after yoga 1 hour without eating or taking a bath.
