However, yoga classes with additional AIDS such as aerial yoga, ball yoga, and yoga wheels cannot be mastered by you with a hatha yoga instructor's certificate.

Among them, Iyengar, though also from Hatta, belongs to another school. I don't need to explain here. Aerial yoga still belongs to the category of hatha yoga. The strictness and objectives of Iyengar's curriculum are quite different from those of ordinary hatha, and it needs to be studied alone.
