Gustoman writes "A new device that hit the market this week may not be able to help you put in fewer hours in the office, but it can help you get a good cardio workout while you're troubleshooting that laptop or reviewing that spreadsheet. Gamercize, a British company, this week launched the GZ PC-Sport & Power Steppe, which is designed to fit underneath a standard-sized desk so someone can sit at their computer or talk on the telephone while using the stepper. Gamercize officials note that the machine is not just a small version of a StairMaster machine that you'd find at the gym. The machine can be hooked up to a keyboard or mouse through a USB port. The user can set it up so they can use the stepper whenever they want, or they can prevent their keyboard or mouse from working unless they're exercising. There are five settings on the under-desk step machine. The lowest setting lets workers simply exercise their legs at an easy pace whenever they want. At the top level, the work out is much harder and the user must exercise to keep his or her keyboard or mouse working. At the lowest setting, a user could burn 100 to 200 calories an hour. At the top level, it is possible to burn as many as 500 calories an hour. (That's like burning off the equivalent of an entire milk shake.)"
