You may have already seen this video. If you haven't, please watch it. If you have, then stand up and move around for a little bit and then get back to the computer.
I've started showing it at some of the presentations I give because I find it so compelling. It doesn't take a lot to start having the benefits that short walks can give you. People have all sorts of excuses about why they can't get to a yoga class (me too) or why they have no time for the gym, or why they have put on weight or why they can't be any healthier. This video to me shows that there really is something we can all do that will make things at least a bit better, especially if things aren't feeling that great in our bodies.
I don't sit at a desk all day but I work with a lot of people who do. I see people on their yoga mats, and that hour/hour and a half is great, but really what's important is what we are all doing the rest of the days. It's good to stretch but if you're not walking during the day and moving your juices around, the yoga will only do so much.
Please get out for a walk on your lunch break, or after work. Make an excuse to do this simple thing. Your yoga will feel better too!
