Serious about tracking your weight? These WiFi scales might be just the thing. They’re not cheap at $370, but along with being incredibly accurate and measuring your body fat percentage, they have built-in WiFi and will upload your weight to a private website every time you weigh yourself. There’s even an iPhone app if you want to check your progress on the go. They take a bit of fiddling to get set up, but once you’ve got everything configured, it really is just a matter of standing on the scales each morning. The Withings.com website is easy to use, and includes handy tips about weight loss and target weights.
There seems to be a strong overlap between fitness freaks and data demons. If you’re looking for a way to track your outdoor workouts, the Garmin Forerunner 405 is your device. No bigger than a decent sports watch, it packs a GPS receiver, 1000-lap stop watch, and a wireless system for connecting to the included heart rate monitor, other accessories, and your computer. After each workout you can upload the data and view the results on an interactive map. See how your heart rate changed with elevation, or compare current workouts to historical results. It’s a brilliant little device..
The shake weight promises a 300% improvement on traditional weights due to a “groundbreaking workout technology called Dynamic Inertia”. I’m no scientist, but the results in my case were groundbreaking hilarity. This device feels like a toy, and I honestly can’t see it doing anything other than make the user look like a prize idiot. Hilariously stupid.
