Not me, but I do yoga.

I did for about a year. Self challenging, and fun !

Never tried it but would like to someday, I hear it's got quite a few health benefits.

It's amazing. "Body meditation", "movement meditation." Incredibly relaxing. Improves balance, coordination, and proxemics and kinesics, I'd reckon. Turns your body into a beautiful, moving work of sculptural art. Ultimate low-impact; great for seniors. Some of the Chinese medicine principles can seem a little woo-ey, but you can ignore that stuff if you like and the total package is still awesome. 10/10 would recommend.

I was a Tai Chi instructor for awhile - mostly Chen and we used the modified Yang 24 as an intro. It's great for relaxation, helping older people to stay active, and things like that. I was a head instructor at a place and learned it to help rehab a training injury.

My biggest grumble is that it draws a lot of woo woo into class. People making spiritual claims and all the metaphysical stuff that has no basis in reality. Since I call bullshit on it, it makes me unmarketable to a big part of the Tai Chi demographic - people that want religion in their martial art without having to actually spar. Because of this, I'm backing away from it and starting with things that are a bit more practical and allow for relationship in the study (i.e. sparring).

In short, it's a good tool if you use it for the right things.

Did you have some question in particular?

Tai Chi Chuan, .....flowery, not very practical. I have long since modified.

very relaxing while contributing to alertness. Very good for balance control for seniors. Helps to develop and maintain positive mental attitude.
