Yoga is great. My only gripe with it is that yoga and meditation are frequently associated with the divine in India because of which the "yoga industry" is full of charlatan hacks who try to amass a following kinda like how Gandhi did. If you look at this list of modern yoga gurus on Wikipedia, many of the recent ones are hacks as well. I can only speak of the ones that are alive because I don't know about the older ones. Yoga (and ayurveda) is also the pride of Hindu fascists who like to bask in the false glory of a mythologised past where yoga (and ayurveda) was a cure to a multitude of ailments, an art which now has supposedly been forgotten about due to the rampaging colonisation by Western ideas. They take the popularity of yoga in the West as affirmation of the idea that India of the past was the most advanced civilisation and other idealist notions like that.

Mostly though if you go to a normal gym which has yoga classes, it is usually fine and normal. But there are a ton of "foundation" run by aforementioned hacks. My neighbours tried to indoctrinate me into one when my parents told them I was depressed. It was extremely stupid.
