I see guys posting here about losing weight instead of losing fat. Here is a really simple and useful formula.
Men's %Fat = (-98.42 + 4.15*waist - .082*weight)/weight,
Women's %Fat = (-76.76 + 4.15*waist - .082*weight)/weight.
For our "model woman" who weighs 132 pounds with a 29" waist,
%Fat = (-76.76 + 120.35 - 10.824)/132 = 24.823.
There are more complicated formulas, and I have seen inaccurate results with skinfold calipers and electrical impedance measurements. This formula is great because it tells you to get big with a small waist. You will need to get strong, with big legs, ass, back, chest, and shoulders.
