Now on the Internet you can find many video tutorials in the public domain. Before starting a lesson https://www.julianalucky.com/yoga-for-kids, ask who is conducting it: read reviews about the teacher (preferably on third-party resources, and not where the video is published), visit the website or page / account of the teacher to get an impression of his competence, if possible, chat with those who are already studying with this teacher, or at least watch their progress, feedback, complaints, etc.
The quality of yoga teacher training, unfortunately, is not regulated in any way, so a simple YouTube search can lead you to promoters who do not even have a basic 200-hour hatha yoga teacher training certificate. Not to mention the sufficient experience of personal practice (from 5 years). Responsibly approach the choice of a teacher. And pay attention to his culture of speech, the clarity and accuracy of instructions, the ability to give intelligible feedback in comments, during live broadcasts, etc.
Don’t be fooled by spectacular splits and ring grips, which are easily demonstrated by a yoga instructor. Since these bizarre forms are often based on a predisposition to connective tissue dysplasia (an anatomical feature of naturally flexible people). Pay more attention to the quality of adjustments of basic asanas and the level of body control in balance forms that require painstaking work, mental composure and physical control (handstands, standing and sitting balances on one leg, asanas with an emphasis on one arm and one leg, etc.). .P.).
Following these recommendations and common sense, you will definitely find a suitable option and format for online yoga lessons, and your independent practice will not only be safe, but also effective, developing and even healing.
