Ive been cutting and eating right and have had good results. 20lb in about 2 months. This is the only gauge I have to go by and its really sucks not knowing what % of that weight was hard earned muscle. The electronic bodyfat scales are shit (I own one and know its way off). My question is this, Im considering buying a caliper. How hard are they to use and which ones have anyone had consistent good results with? I see electronic ones too. Whats the deal?
