Step-by-step explanation:
According to William Sheldon, somatotyping is a method to determine a person's personality based on their body type. This includes three components: endomorphy, which refers to a rounder body type, mesomorphy, which indicates a more muscular and well-built physique, and ectomorphy, which describes a leaner and more delicate body structure. Sheldon's theory proposed that these body types are linked to certain personality characteristics and behavioral tendencies.
