I like to keep a handle on my weight and general fitness levels and I can wholeheartedly say that the Whitings Body Analyser scales are one of the best bits of technology to help me with that. Mainly I use it to track my weight, but it also records your body fat percentage and heart rate when you step on it. That would be pretty useful in its own right but the main benefit I have found is that it sends that data to your own private Whitings account and you can login and see how you’ve been getting on!
This is some of what it shows you in graph form.
In addition to that it constantly monitors CO2 levels and you can connect it to your smartphone too if you like.
All in all, I’m very impressed!
