The Polar BodyAge fitness assessment determines a single universal assessment unit with just a few simple tests – the physical body age. This promotional video goes through an actual test showing off all the features. It is a pretty cool universal system with all the tests integrated and results and fitness programs produced from the results. I particularly like the sit and reach test, using a cable system built into the unit. See more on the Polar BodyAge assessment, and the Polar Fitness Test (OwnIndex).
