Malinda has never had to worry about her weight. She eats pretty much whatever she wants and does not gain weight. Still, Malinda can’t do a pullup or burpee in gym class. If Herbert Sheldon were asked to assess Malinda’s body type, which one would he MOST likely describe her as?

Sheldon’s ectomorph body type is typically thin and has difficulty gaining weight, which fits Malinda’s description of eating freely without gaining weight. Being unable to do pullups or burpees does not by itself determine body type, but the weight-related clue points most strongly to an ectomorph. The correct choice is ectomorph.
