Yoga is for people in good physical condition. Or it can be used therapeutically. It’s controversial to say, but it really shouldn’t be used for a general class.
That's strange to me, because from what I know practicing yoga to a lot of people means following a specific mindset, diet, doing breathing exercises and holding various quite simple positions, I don't see how that can be dangerous and describing it as all headstands and neck twisting later in the article seems like a deformation of the original philosophy.
What is really deeply wrong with the article in the end is that it blames a specific kind of activity as the source of problems, so that people who read it maybe will think that yoga is dangerous and choose running instead, but will be left with no understanding of the fact that what really causes most of the injuries in most of the sports is ignorance of technique and basic safety restrictions, ignoring warnings signs from the body and most of all not learning enough about the given activity along with practicing it. Those people will end up having the same problems in any sport they choose. Yes, holding a headstand for five minutes can cause serious health damage if you have any problems related to your blood vessels, but the same thing can just as easily happen to a person doing a decline bench press in the gym or when training traditional gymnastics. Yes, pushing your body into unnatural positions when it's refusing to do it and signalizing pain will cause joint issues.
Guess what, education is as much needed for sports as it is for anything else.
Moreso, just because you know what you're doing or experienced doesn't mean you should do it. Knowledge of how to stand on your head, and the wisdom of if you should stand on your head are two different things.
Many instructors probably shouldn't do things that their students are doing. Why? Because they might be teaching 3 classes that day, and the student is in there three times a week.
