It depends on how long you spend every day. If you concentrate on practicing yoga, you can start in half a year. Personally, I think learning yoga should not be too difficult to pursue posture, because after all, it is not competitive. Even as a yoga instructor, being able to do some yoga postures that make ordinary people feel difficult can certainly increase their charm and more followers, but it doesn't mean that those who can only do some simple postures can't become yoga teachers. In fact, fluent and comfortable introductions and your own temperament are the most important. It would be more perfect if you could be familiar with the effect of yoga posture. In addition, you need to master some health knowledge.
1, find a professional yoga instructor training class for professional study. It is difficult to practice yoga well, which requires professional training.
2. Training is only the basic thing, so you need to further strengthen your practice and increase the difficulty of your skills.
It is ok to take some certificates if necessary. If you don't have a certificate to participate in the competition, it is better to win the prize.
4. Then you can apply for a job in some gyms or start your own class, so that you can teach yoga.
The process is simple to say, but it still needs your own efforts.
