Do people who workout seriously for their figure always feel inadequate?

Do people who workout very seriously always feel like they are not good enough? I hear that some guys who workout a lot always feel small and that some girls who workout are constantly trying to slim down or tone up and it's like both genders are never satisfied with how they look. Is this very common? Some of the stuff people do in competitions seems very extreme.
