How to calculate your body fat percentage
A: (Total body weight x 1.082) + 94.42
B: Waist measurement x 4.15
A-B=Lean body mass
Total body weight – Lean body mass= Body fat weight
(Body fat weight x 100) / total body weight = Body fat percentage
A: (Total body weight x 1.082) + 94.42
B: Waist measurement x 4.15
A-B=Lean body mass
Total body weight – Lean body mass= Body fat weight
(Body fat weight x 100) / total body weight = Body fat percentage

This is a bit confusing.
When i measured my bf at the gym, they had me listed as 15%.
But using this formula, it has me listed at 22.6?
Weight is 165, waist is 35".
What method are your using at the gym?
At the gym they had the bodyfat machines, where you stand on it and they measure your weight and it brings up the bf%.
With this it says im overweight when im not...
If you are working out atleast 4 days a week, that machine should have a setting for you to change from "normal" to "athlete". If the machine does not have the ability to change the settings then its probably not accurate. You cant measure someone who sits home all day and an athletes body fat on a machine under the same settings.
According to the measurments you gave me, i would say the solution you got from this formula is more accurate than the scale at the gym.
Hello,
The machine for me also had much less than this formula.
I'm listed at 23% when at the gym, as the athlete setting it had me at 17.5%...
I workout 3-4 times a week, jogging 5 times a week.
That is pretty odd, i get the same on both the machine and the formula give or take a percent or two.
My brother reads 9 on the machine and 10 with this formula.
Either way you choose to measure your body fat it wont be 100 percent accurate unless you participate in hydrostatic testing.
Whether you decide to use the machine at the gym or the formula listed, it is important you continue using the same method in order to get a more accurate record of your progress.
Thanks guys!
Thanks Muscle Monsters, i use the machine that has you input all your stats and then you hold it out in front of you.
That machine had me at 17.something and this formula had me at a little more than 18. Pretty accurate i must say.
