Weight watchers scales are way off. Mine will say 14% on empty stomach and up to 17 after breakfast. I stoped checking it with that haha I am going to looking in to this one. I will eventually get calipers when I am lean enough not to be shocked when I check it for real haha
Agreed with tape measure. Scales are way off, calipers are good if you use enough points and a good measurement taker but quite a bit of human error in it. Measurements are the way to go.
If you want a real BF test, go to a gym/college/somewhere that they offer underwater weighing/bod pod/calipers etc. They’ll usually take the average of the three and you get a pretty good estimate.
