Today at the office, we got a little memo talking about doing a five minute exercise each day to "take some time for yourself." As a joke, my colleague read it out loud to me, and I did all the exercises at once.
Somehow, this miraculously reminded me that I deeply love stretching, and stretching at work makes you feel better about being there. I'm sure you can find the actual "Workday workout" pdf online (and if you can't, and want it, let me know and I'll email you a copy), so I'll just give you my new stretch, which I'm planning on doing at least once an hour from now until someone tells me to stop.
Sit up straight in your chair. Shrug your shoulders up to your ears. Raise your arms above your head, interlocking your fingers so that your nails face the top of your head. Place your right ankle onto your left knee. Keeping your back straight, bend forward as deeply as possible, until your stomach and face are flat on your lap. Rise. Repeat, switching legs.
I hope this new stretch improves your workday as much as it improved mine!
