Thanks for all the feedback about the yoga and pilates classes. Maybe I was jumping the gun a tad by thinking I should buy a year-long membership after taking only one class. (Actually, I was only going to buy a 3-month membership. Much more reasonable.)
I went to a beginner yoga class last night and then I bought two 10-packs, one for yoga and one for pilates.
I cannot adequately describe how beneficial this yoga class was for me. I felt relaxed and appreciated and safe and content. Is that how yoga usually goes? I've only done it maybe 2 or 3 times in my life and it was always in a big class with very little personal attention.
This class only had three students. The instructor (who is the same person who teaches the pilates classes) showed us (me, really) variations on every pose. With almost every pose she walked around to check that each of us had more or less the correct form.
She said the yoga classes never get much bigger than a few people. I find that surprising, but maybe it's because there are other yoga studios all around.
I kind of want to go every day, but I'm going to wait until next Monday to go back. Maybe I'm just a little bit too excited about taking these classes.
