Thats fabulous. Can I ask what the BF% means?? I've seen it on a few posts ... a bit new to this :) 

@teamshackleton body fat percentage. Although a precise value isn't possible using scales that this feature, it's a stat I still like to track as a trend as it's a main goal of mine to get down to 15%.
