Thanks, Robin! I really appreciate the tips!
My goal for yoga seems to be in line with what you're describing. I was/am looking for a new challenge, a way to stretch myself, figuratively and literally. From what I've read/seen of yoga (which, admittedly isn't an awful lot), it seemed yoga and tai chi would be ways to increase both flexibility and self-awareness, if that makes sense. A way to help find/maintain balance.
And just as you've said, the instructor gave at least one, sometimes up to three, alternatives for almost all the poses she had the class do. That was nice.
As far as burning a few extra calories, I think taiko will probably fill the bill there. But, even if it doesn't, that's ok. Calories isn't my goal. I just like challenging myself and these seem like fun, stimulating activities. Helping maintain the mind-body connection.
Of course, if the pounds start melting off for some reason, I'll not complain
