I liked Chair Yoga immediately, and enjoyed doing breathing and stretching exercises sitting in a chair. We stood up for some asanas, and I discovered I wasn’t using the chair at all. I was flexible from all my previous years of practice, though my balance needed more – balance. When the four sessions came to an end, I promised myself I would continue to practice yoga a few minutes every day.
We writers sit at our computers for long stretches at a time. We do our best writing when we lose track of the passing minutes. Still, it’s important to get up occasionally and stretch. Walk around. Do a bit of yoga. It's best to take classes with a certified instructor who will let you know if you're doing each asana correctly. There are many yoga sites on line. The one I’ve used and like is Desktop Yoga: http://www.mydailyyoga.com/yogaindex.html
