I remember when I was studying my undergrad in exercise science we did a lab with checking body fat% using different methods. Calipers put me between 13-11%, the bio-electric scale used by the wrestling team said I was 10%. The bodpod (most accurate, next to hydrostatic weighing) put me at 17%. when it said I was 17% I couldn't believe it, I thought it was bullshit. Now I realize I was still skinny-fat but didn't want to admit it.
