Somatotyping is a system used to classify the human physique into three fundamental types: Ectomorph, Mesomorph, and Endomorph. While most people are a mix of these types, understanding your dominant traits can help you tailor your diet and training for better results. This calculator uses a series of simple questions about your physical characteristics and tendencies to provide an estimate of your somatotype. It's a great starting point for understanding your body's natural predispositions.
