True. Julie has an ectomorph body type, which means she is tall and thin with long arms and legs.
There are three basic human body types. 1) Ectomorph Thin build, long limbs, narrow hips and clavicles, small joints (wrists, ankles), stringy muscle bellies 2) Mesomorph Wide clavicles, narrow waist, thinner joints, long and round muscle bellies. 3) Endomorph Block, thick rib cage, wide/thicker joints, hips as wide or wider than the clavicles, shorter limbs
Ectomorph is a thin body type in which an individual is having a skinny body. An ectomorph is a person with small and light build with long thin legs and arms.
Such a person has stringy muscles and shoulders are thin with less width. Ecto's are one of the three body types.
