Calculating body fat %

Invest in a tape measure...........I bought mine at Walmart (fabric department) for maybe less than $2-3.
Go to this website, or simply Google "body fat calculator":

It's not exact, but it will give you a rough idea of where you are, and if you use it consistently, it will also give you a rough idea of how much body fat you are losing over the course of time.

Hi, you must take measures of your: neck, waistline, height and hips. This is a approximate calculation!
