Hey bro I do bodyfat test for a living. I would say that 90% of people that do them and I am talking professionals...dietitions, trainers, etc. do not know how to do this. I would say around 8% you should start seeing your second and even third pair of abs. The lowest I have been is 9% and had around a 30-31" waist size and could see obliques very well as well as upper and middle abs.
I love it when these fat asses come in and tell me they are like 20% for women and 15% for guys. Then I look at them and I know I can get a couple of handfuls of rolls of fat in my band. My gf is around 20% and she has pretty nice definition. Anyways this fat bitch who trains with this fat bitch trainer told me see was 20% I about shot myself and my client who also was a female and also fairly lean around 20% about died laughing. The fat dumb bitches at the gym go round and round, round and round, round and round. I said the fat bitches at the gym go round and round all day long lol...cmon everyone join in and sing...anyways my point is that no one knows how to do bodyfat to save their life.
Seriously I have had two people who did a fair job of it. A dietition at my college and one or two other trainers in my life. Everyone else fucks up and badly like by 10%!!!!!!!!!!
Quick note: If you have the zone diet or go to the bookstore or library and grab it. It has a chart that is fairly accurate I would say within a 3-4% range. I have tested it on me as well as clients. All you do is do your circum. around your waist at belly button level...dont suck in fat ass lol jk...and then around your wrist. Subtract wrist from waist. This gives you a number and you need your bodyweight. The chart does the rest and like I said it gives you a fair estimate. I can do it for you. I have the book...give me the following
BodyWeight:
Waist Circumference around belly button. Do not pull tight making your waist circ. smaller. Also do it in morning on empty stomach.
Wrist circumference. The area were your forearm meets your hand. There should be a bone that pertrudes and this is ususally were i measure.
Let me know and I will tell you what the book says. I will check back.
