It is body fat. You have to be under 20 percent for males and under 28 percent for females. To measure body fat the military uses waist/hips/neck for females and waist/neck for males . To calculate it just google body fat calculator military and like 5 show up. Hope this helps!
If we fail the tape test on I day, will we be sent home?? I am really trying to pass it, but I have to loose 4in off my hips/waist in the next 17 days.
