It's been nagging at the back of my head for a long time now. I finally manned up today and checked to see what it was. It was the thing where it sends an electrical signal or w/e to you and comes back to see what your body fat is. I'm bulking btw. It came back 17%. The guy who measured it told me that since I'm still growing and only 17 that it was fine. I'm about 185 and 5'10 or 5'11. What do you guys think?
