Mesomorphs are one of the three primary body types in the somatotype classification system, which also includes ectomorphs and endomorphs. Characterized by a muscular and athletic build, mesomorphs typically have broad shoulders, a narrow waist, and a naturally higher percentage of muscle mass. This body type is often associated with a more efficient metabolism, making it easier for individuals to gain muscle and strength. People with a mesomorphic body type usually excel in physical activities and sports due to their natural strength and agility. They can often achieve fitness goals more quickly than other body types, making them well-suited for activities like weightlifting, sprinting, and other high-intensity exercises.
