How do you become a certified yoga instructor?

Say "I want to become certified as a yoga instructor." ... To a certified teacher trainer. 

At your local yoga joint, 90% of the time at least one of the teachers has all the certifications and legal/health dept stuff to teach other people how to be yoga teachers. Or else they can hook you up with someone who does. Just like college, class starts in the month of X and goes for Y months, 200 hour cert every Monday at 6pm for 37 weeks, less MLK day etc, however that plays out for the place and time. Then you take a picture with your teacher holding your paper to post to instagram. I'd ballpark $2000 and 6 weeks generally speaking. There are bigger investments with smaller rewards. The obvious issue being will/is COVID going to make yoga impossible as a job? At the moment in my area, it is.

ask someone thats doing it how they did it
