If you still haven't picked up a Nike+ Fuelband or Jawbone Up, you ought to add the Fitbit Flex ($100) to your list of fitness trackers to check out. Like the others, the Flex is designed to be worn on your wrist, and tracks your steps, distance traveled, calories burned, active minutes, and quality of sleep, all of which it syncs to your iPhone or Android device via Bluetooth 4.0. It can even vibrate to wake you up gently. Arriving this Spring in a variety of stylish colors.

Other features include an OLED touchscreen display, a rear-mounted heart rate sensor, a two-week battery life, micro USB port for charging, and Bluetooth 4.0 for low-power wireless syncing to the Withings Health Mate App. Arriving Q1 2013.
You won't be using it to train for the World's Strongest Man competition, but if all you're looking for is enough weight to keep tone while you're sitting at your desk, the Alias Barbell ($150-$200) is all you need.
