There are 3 different body types
The ectomorph is characterized by long arms and legs and a short upper body. They also have long and thin muscles. Ectomorphs usually have a very low fat storage; therefore they are usually referred to as skinny. An example would be a basketball player.
The mesomorph is characterized by a good rate of muscle growth. They have large bones, solid torso combined with low fat levels. It is also noted that they have wide shoulders with a narrow waist. An example is an Olympic gymnast.
The endomorph is characterized by an increased amount of fat storage, due to having a large amount of fat cells than the average person. They have a wide waist and a large bone structure. An example is a power weight lifter.
