In addition to starting up with the meditation group, I've started going to yoga classes. Yeah, yeah, look at me, all zen and shit.
Anyway, I'd just like to point out some of the pros and cons of yoga, from the perspective of my very limited experience:
-It's very relaxing
-It improves flexibility
-It promotes a sense of peace
-That cool vibrating feeling when you chant "Om" (even though I wanted to laugh the first time)
-Trying not to fart during the ass-in-the-air poses is really distracting
