How accurate are those BF analyzer machine thingys. The ones that measure BF, Muscle Mass etc... I get on the machine at my gym maybe once a month. Since I last got on the machine my BF went up 0.3% my Muscle Mass went down 1.5 lbs. I am lifting heavy and even more heavier. The number on the scale went down 7 lbs.
The thing I am most upset about is the 1.5 lbs loss in muscle considering I am lifting the same or more and getting in my protein.
