Note that with very muscular physiques such as bodybuilders, the BMI result will indicate overweight since no
account is taken for well above average muscle mass.
Body fat
The following body fat percentages are guide values (contact your physician for further information).
A lower value is often found in athletes. Depending on the type of sports, training intensity and physical con-
stitution, values may result which are below the recommended values stated. It should, however, be noted that
there could be a danger to health in the case of extremely low values.
