The term mesomorph refers to a body type (somatotype) characterized as being well muscled; some references describe it as being with wide shoulders, long arms and a narrow waist.  An example of a mesomorphic person in sports would be a typical weightlifter, shot putter or sprinter. Generally, mesomorphs rank high on strength, speed, endurance, power and agility.
