oh god, trainers are horrible with everything. Did they use calipers or the stupid "hold this in front of you" type mechanism? I remember I was signing up for a gym and the guy was like "do you want your BF% measured?" im like "hell yeah i was curious to see what it was".....it came out to something near 5% ......I started laughing and said, "really, damn then I dont need to join a gym now do i!" . I knew I was above 10, all my abs were barley visible.
