I do it at home with my wife. She found a youtube instructor that specializes in routines for chronic pain conditions that works really well for her. Like I said I just like it because it helps me regain mobility in my shot hips and knees. One of my gyms used to offer capoeira classes on Saturday but a very slowed down version that was basically yoga/cool-stretching

It absolutely can be a meme, but I can attest that having a more sophisticated stretching routing helped me with neck problems that had persisted for over a year.
