Thank you ladies.

Re: yoga...
Never in a million years would I thought I'd be doing yoga regularly, but here I am three times a week, for about 3 months already now.

Like some of you I'm noticing that yoga is making me much more flexible and increasing muscle strength while adding range of motion to all my connecting tissues and joints. Biking has never done that, biking's been more of a leg muscle and cardio/lung help. This regular yoga stretching and weight bearing is changing how my body feels in ways nothing has ever done before. Amazing! I don't think i'd notice it much if i was doing only one class a week though. I spent the first 6 weeks in almost constant soreness as my body started adapting. Now not as bad, more of a pleasant soreness.

I also like the ritual of going to class and sitting in a roomful of people together. Hard to have that kind of self discipline to do it at home regularly. I'm not in it for the spiritual aspect (I'm an agnostic), but it's calming and pleasurable in other ways to me. My whole spine especially from head to tailbone is just loving yoga- the twists and stretches are feeling sooooo good! Even my fitness walking and contra dancing cant' twist and stretch me like yoga does, and my body is thanking me in the mornings when I first wake up. This in itself is a big thing for a 58 year old woman- to feel no creaking in the morning!
