Most regular yoga students, after some years of practice, find themselves stuck in 90 minutes of classes. They keep doing their yoga practice and attend classes in the yoga studios, but somewhere deep inside, and they feel the need for deepening and understanding their practice.
Workshops generally fulfill this need either by the studio teachers or visiting masters who have mastery on some branch of yoga. But an issue comes with random seminars and workshops; they aren't aligned with each other. Most students cannot connect the learning from them, and they learn mainly in patches and finally get confused at the end.
These issues are solved mainly by long terms courses like 30, 50, or 100 hours on very particular topics or either comes in the offering of 200 or 300 hours yoga courses.
The 200 hours is a foundation course where you learn the basics of yoga in terms of philosophy, anatomy, yoga postures adjustments, breathing methods, and small sections of teaching methodology. Well, the primary purpose of 200 hours to give you a regular and more explorative practice rather than convert you to yoga teachers straight.
Teaching yoga requires patience, understanding of concepts and students' needs, and above all, personal experience with yoga methods. Therefore, yoga teachers should have above average level yoga mastery on asanas, pranayama, diet control, and their own lives.
The 300 hours is an advanced course, where you master the unique practices of yoga in-depth. For these courses, you have to build a solid yoga practice before entering into the curriculum. Here, you learn methods of yoga and connect it with yoga philosophy and psychology.
The good yoga teacher's training has following signs-
They train you as a yoga practitioner first rather than a yoga teacher in the early phases.
The course content on yoga psychology should help you to discover yourself and real needs and goals. Not goals that were given to you by society or your urge to prove yourself.
The teachers share their own experience and mastery. If you cannot do by yourself, you cannot teach it also.
They motivate you to bring a dedication to learning and practice.
