For those who wish they knew what sort of stretches they could do at their desk, check out this YouTube video. It’s about three and a half minutes long, and goes through 12 stretches—illustrated!—covering most of the upper body. The video is accompanied by soft, elevator-type music.
The video recommends you do these stretches once every hour or so. I just went through it, and my upper body feels so much better! Highly recommended!
Cheers,
Julie
