I am speaking about an Indian yoga expert, Subodh Gupta, teaching in India and elsewhere.
Quotes:
“However, like any other science, yoga is a precise science. The question is: are all yoga exercises safe to teach through TV media…”
Similarly, there are other yoga postures which require great precaution…
Subodh Gupta challenges actually even teachers like Swami Ramdev to answer these questions.
I saw several posts on this forum with people injured by practice, eg the thread “help with my knees.”
Maybe this forum can help more in this regard. I compliment InnerAthlete for his competent efforts.
