Body Fat Caliper

So this one is for all you tech geeks out there. It's important to work out if you have your nose down a DIY projekt all day or sits in front of your 3Dprinter twenty four seven. Your body can match your brain. ;-)

The Skin fold caliper is a device which measures the thickness of a fold of your skin with its underlying layer of fat. By doing this at the key locations can be a quite accurate representative of the total amount of fat that is on your body, it is also possible to estimate the total percent of body fat on your body.

If you have a smartphone download this app https://play.google.com/store/apps/details?id=m2m.bcf (it's the best i have tried so far) and start measuring. As a fitness freak this is a real booster.
