Hello everyone,

I am not sure if i am posting on the right place.

Anyways, Could anyone tell me if Waist-to-Hip ratio is ideal way of monitoring the progress.
What confuses me is as i am bulking and after every couple of weeks i take my measurements and calculate the LBM and Fat i have gained. Actually i don't calculate it but
i put my measurements on a website called www.mybodycomp.com and they tell me my progress. I did my measurements last week and it showed me 2 pounds of fat gain and 1 pound of LBM gain. It just did not seem right. I also do Abs and Obliques. Could this be the reason why my waist to hip ratio has increased and he website is showing more fat gain. I currently don't have calipers. Also, as i see myself in the miror i feel that i am getting bigger overall and stronger.

Have fun always

From what I can tell the website uses tape measurements to calculate your bodyfat percentage? The site does not use skin caliper measurements or DEXA measurements?

If that is the case then the measurements are extremeley variable for calculating body composition, and therefore LBM/fat ratio. Also the measurements are not really going to stay consistent as your body changes on your bulking stage.

In short the program may be beneficial for tracking the changes in bodyparts (for example if you want to increase your arm size), but for body composition it would be far better to get a 10 fold skin caliper test done by a trained professional or a DEXA done if you have the equipment available.

Even a one site Accumeasure is going to work better then that method!

Hey Folks,

Hmmm Thanks for that and i better invest for some good callipers. How about Accu-Measure Fitness 2000. Is it any good?

Please advise!!!

There are pros and cons to calipers. The cheaper models are virtually the same as the more expensive ones IF in the hands of an inexperienced practitioner. Even the better ones are highly reliant on tester ability for reliable and accurate results. If it's always YOU testing YOU, and you do it the same way each time, then reliability increases. In other words, even if you do it wrong, if you're doing it wrong the *same way each time*, you'll be able to gauge progress, although your numbers may be a little off.

Hey all,

I did 7 point test for bodyfat and got the numbers. Then i did some calculations and its showing my calculation as 27% bodyfat. then i went to a website http://www.linear-software.com/online.html and got the calculator do my measurements and to my surprise it is showing 18.33% bodyfat. I am totally confused as to what is correct. The equation i used on my own to calculate body fat is

Seven points (pectoral, midaxillary, tricep, subscapula, abdomen, suprailiac, and thigh)
--------------------------------------------------------------------------------------------------
Body Density = 1.112 - (.00043499)(sum of seven) + (.00000055)(sum of seven ^2)-(.00028826)(age)

db= 1.112 - (.00043499)(134) + (.00000055)(17956)-(.00028826)(age)
db= 1.112 - 0.05828866 + 0.0098758-0.00662998
db= 1.112 - 0.06816446 -0.00662998
db= 1.112 - 0.07479444
db=1.03720556
Once again, you will use the same formula for body fat as the 3-point test:


BF% (percentage body fat) = [(4.95/Db) 4.5] x 100
bf = 27.24


My actual measurements are:-
pectoral-10
midaxillary-15
tricep-20
subscapula-20
abdomen-30
suprailiac-19
thigh-20

I will appreciate if someone can help me with correct percentage.

Have fun always

I don't have the correct formula in front of me, but I think that looks right. More important for your purposes is to test it the same way with the same calipers every time.
