You can do yoga in a chair, for sure. Sometimes you need to do yoga in a chair because doing yoga on a mat or even a spot on the floor is not appropriate. Sometimes you're in a seminar and start to get stiff. Sometimes you spend 3 hours in a car to get to a workshop where you will sit for 5 hours and you need a stretch. Torsten and I needed a stretch last night in our Landmark Introduction Leaders Program in Montreal. So we did a little chair yoga.
Here's what you do...sit up tall in your chair, pressing your sitz bones down and elongating your spine. Breathe. Even a little ujjayi breath can bring you present quickly. Then do some version of 6 movements of the spine. Any order is okay. You can turn in your chair and look behind you one way, and then the other way. You can reach up and go side to side with your torso a la Half Moon. And placing your hands on your thighs you can try a vertical cat/cow. If you want to go on you can bring a leg up, holding your thigh into your torso and swtich. Another stretch is to cross one leg over and bend forward. Switch sides. Those moves got us through until 12:30 when we got back into the car to return to Ottawa.
I've led Chair Yoga workshops and there are loads more moves I could show you if you ask me. Just because you don't have a mat and aren't all dressed in lycra, doesn't mean you can't do yoga!
On another note... The DVDs are being shipped and are $20 and if you contact me I'll get one out to you.
