An Ideal, for me is just that, an ideal not a reality. It can give us a target to aim for if there is something we are not happy with, but shouldn't lose sight of the fact that we will never attain it. Near enough should be good enough in this case.
Personally my ideal body is one like Xena, the Warrior Princess. I am never going to lose my broad shoulders, so I will embrace that, and aim at being reasonably physically fit rather than a stick insect.
