This formula designed by “Broca” has a limited value.  
As long as there is no new method to determine the 
ideal weight, the image we have of ourselves, tells us 
more than any other number. But a lot of people feel 
better when they can compare themselves with 
figures and numbers. Therefore it is sensible to take 
into account a few well known formulas as the body 
mass index (BMI) and with some reserve, the 

waist 

to hip rate

 (girth waist – hip). 

 
Body Mass Index (BMI) 

The BMI refers to the connection between weight and 
body shapes, which allows us to set up a better and 
exact standard than the “Broca” formula.  
 
BMI = present weight (in kg) : height in m².   
Ex.  A man of 70 kg and 1.70 m high has a BMI of 
70:1.7m² = 24.22. 
 
In the table beneath you can situate yourself.  These 
values are a guidance and are not guaranteed, 
especially not for sick persons, children and elderly 
people.

Fatpercentage 

Body fat expressed in percentage tells us more than 
numbers about the relation weight/waist. To 
determine the fat percentage we have to take into 
account some parameters depending on age. You 
can determine your fat percentage in different ways. 
You even find many balances who also can measure 
your fat percentage. If you want to lose weight, then 
the fat percentage is more important than the weight 
itself, because it is the fat you want to disappear.

Connection waist – hip (waist to hip rate) 

You have determined a higher fat percentage than 
normal in above chart. This fat can have a different 
impact on your health. With a simple test, which you 
can do at home, you can determine if you have a 

higher risk for cardiac disorders. To execute this test, 
you have to measure the girth of your waist just 
above your belly button, without holding in your 
stomach and in a relaxed position. Than measure the 
girth of your hips on his widest point. Divide the girth 
of the waist by the girth of the hips. If the result is 
lower than 0.9 (for men) and 0.8 (for women), you 
don’t have a higher risk for cardiac disorders than 
normal.   
 

Measurements 

Do also take your other measurements, besides your 
waist and hips. If you want to improve your 
silhouette, these measurements can show you the 
changes your body made during training. This 
method is still the most precise, fastest and cheapest 
one. Please pay attention you take your 
measurements always on the same place. We advise 
you to take measurements of the following parts : 
girth of the neck, shoulders, breast, arms, upper 
arms,  waist, hips, thighs and calves. 
 

Figure 

Talents are often seen as interesting and attractive in 
daily life. This is also the case for our figure.  If it 
doesn’t measure up to certain criteria, we find a way 
to change this. Unfortunately we also have to say 
that the “Fred Astaire” type not often becomes the “ 
Arnold Schwarzenegger” type. This is also true for 
our body, the “Rubens” type will not become easily a 
“topmodel”. So before we begin fighting windmills, it 
is probably more sensible to take into account our 
figure. Do we all have to be “topmodels”? Our 
physical appearance depends strongly on the time 
we live in. Therefore it is rarely that the body types, 
you find next, exist. Most people among us are a 
combination of different types. 

Leptosome/ectomorphe type

Features : 
 

• 

Wider pelvis than shoulders 

• 

Very supple joints 

• 

Weak muscle development 

• 

Weak blood pressure 

• 

Increased pulse in rest 

• 

Weak circulation (less endurance) 

• 

Cold hands and feet, dizziness when you stand up 

• 

Intense activity of the nervous system 

• 

Weak metabolism (hard to gain weight) 
 
Contradictory to other types, this type will not be 
suitable for performances which include power and 
endurance. An adapted training can improve these 
shortcomings even though the starting points are not 
always favorable. The figure of the ectomorphe types 
often creates envy by other types. This type has the 
privilege to eat as many as he wants without gaining 
weight.
