Frequently Asked Questions

How to use?
Select your gender, enter your wrist circumference in centimeters, then click Calculate to determine whether you are an ectomorph, mesomorph, or endomorph.
Why wrist circumference?
Wrist bones barely carry fat or muscle, so their circumference is a stable indicator of skeletal frame size and body type (the Solovyov method).
