If you want to learn yoga knowledge systematically, then you should go to a yoga instructor training school. If you just want to keep fit, you can also go to a yoga studio to study.

To become a qualified yoga instructor, we need a long time, not just a day or two. I also have a lot to do with myself in practicing yoga. As the saying goes, it varies from person to person. Some people learn things faster and have better flexibility, and students adapt quickly. Some people are stiff and need long-term exercise.
