I bought this little book at the Tillamook Forest Center the other day when Mark and I were there on our play day. I've been practicing the yoga poses in it for the last two nights. Boy, was I surprised to wake up sore this morning! I hadn't really trusted that the yoga poses could be that much work, I guess. There are a couple of them I can't even begin to do, but for the most part, I'm finding this to be a useful little book. I want to keep practicing the poses. I thought they would be good centering stretches, but maybe they'll help me to build some strength, too!
