It's a great program; every hour or two hours, or certain number of keystrokes, a Tibetan bell rings and a window pops up asking if you have time to stretch. If you do, you click okay, and the stretches pop up on the screen. When you roll your mouse over an individual stretch, instructions pop up in a window.
It works on both Mac and Windows computers. Go here to download:
BTW, we were kind of amazed to learn this week that our book Stretching sold 38,000 copies in China last year.
