Get Exercise is a small application that, once setup, reminds you to do stretching exercises (with pictures), aerobics (walking, jogging, etc.), circuit training (multiple exercises during a less than 10 minute time period) and a series of 1 minute exercises every hour. Everything is configurable by you. Download the ZIP file from here. getexercise
