Chance are that you're familiar with pedometers that record the number of steps you take in a day, they're a great fitness motivator but with one minor drawback - at the end of the day they present a bunch of numbers which are next to meaningless.
Enter stage left, The Fitbit Flex - a wrist-worn fitness tracker gizmo that is worn in a nifty silicon wrist band and can wirelessly sync with a PC, Mac or smartphone to keep you motivated via goals and up to the minute progress reports.
Soon to launch in New Zealand, punters can pre-order their flex via the Fitbit website. Consisting of a small water resistant tracker module and a silicon wrist strap plus a USB charger (wrist straps are available in small and large sizes and in a range of different colours).
The strap has a small transparent gap that displays five tiny white LED lights - each of which represents 20 per cent of your daily exercise goal. Although the LEDs are not on continuously, they can be woken up by giving the Fitbit flex a few taps.
The Flex is also water resistant which means it can handle a shower or briefly being submerged.
You'd also be forgiven for thinking that wearing a wrist strap would be intrusive but after a several days I can attest to almost forgetting I had the Flex wrapped around my wrist.
Inside the strap is a pencil eraser-sized electronic tracker that records your movement so you can keep track of the number of steps taken, the distance walked/ran, and calories burned. Additionally the Fitbit will also monitor sleep patterns.
