watch

I've been testing a gaggle of walking watches. Some are variations of pedometer watches, while one controls your iPod. Here are the first two.
Let's start with the Heart Rate Monitor/Pedometer Watch for Dummies. It arrived promptly after ordering it online, but with a dead battery. Luckily, the vendor had an easy way to do an exchange and in another couple of days I had a working model.

While there's no shortage of iPod remotes out there, Scosche has taken what seems like a pretty obvious idea and actually produced an iPod wrist remote. Strap it on watch-style, and you're in control, as long as you're in range of its RF signal. http://www.engadget.com/2005/11/14/scosche-remote-puts-ipod-controls-on-your-wrist/

The portable geek gym consists of a pair of sunglasses with a half-inch square LCD screen incorporated into the right lens, a Pocket PC with video output, a pedometer that can be attached to a running shoe, a Spot Watch that can receive and display news from the Web, headphones and a GPS unit.

The gym requires actual running, but it helps with the motivation part. Because the GPS unit is in constant communication with the Pocket PC, the system always knows where the runner is. Upon reaching certain coordinates, the system can rev up video and audio clips to keep the runner entertained while he's out beating the flab.
