How Do I Calculate Muscle Mass Percentage

Every wondered how you caluclate your muscle mass? Just follow the simple instructions below.

1
Weigh using body fat scales and take a note of the body fat percentage

2
Minus your body fat percentage from 100 to get your lean mass percentage
Example:
100 - 30 = 70% lean mass

3
Divide your lean mass % by 100
Example:
70 / 100 = 0.7

4
Multiply your lean mass by your total body weight.
Example if I am 165lbs:
0.7 x 165 = 115.5 lean mass

The value of maths in everyday life

I appreciate your simple formula for measuring muscle mass percentage. It is quite easy to follow and is a proof of what I have always believed: mathematics is a valuable subject for our everyday living.

I love the idea of it but I have never tried to figure it out myself. How much do those scales cost? I looked at some a few months ago and the only ones I found were really expensive.

Be aware that none of the bio-impedence scales you get (Tanita and the like) are very accurate at all when it comes of calculating body fat %. They are so influenced by hydration that they usually give wildly varying readings.

I would say the only way to use them is

Same Day, Same Time Each Week

Ensure everythign is the same. e.g.. Get up, go to toilet, drink 500ml water, wait 1 hour, then measure.

Even then, all they can really offer is a trend (hopefully in the right direction), the actual number value is pretty arbitrary as it's most likey won't reflect your true body fat %.

Callipers can work, but unless you are well practiced, getting that right is not easy. Many exercise professionals can't even offer reliable measuring.

I personally think that it is often better for people to focus on the measurements with a tape measure. This allows you do see progress in various areas, and get an idea of where the weight/fat loss is coming from.

I use a 9 point measuring system, taken once a week, and entered on a spreadsheet. Heree is an image link to the locations I use
