Seems to me there’s a wide margin of interpretation to what “looking good” may mean.
I used to work out daily, mostly for training for sports, but with kids, job and life I’ve lost interest and work out occasionally because I ***have ***to, not because I want to. I never thought that I’d lose the desire to exercise.
Anyway, in high school there was this kid who was in the weight room daily…not terribly “big”, but in pretty good condition. I’d say out of his two-hour daily workout, he spent 45 minutes looking in the mirror. THAT is vanity.
IMHO, pushing one’s self past healthy to fit in this or that size dress or pants size is vanity, or bulking up to impress people at the beach or pool is vanity. Bulking up for sports training can go either way.
Not to mention that there are plenty of “fit” people who could look better…that would be pushing vanity.
It’s all in where one’s motivation lies. If a person wants to be healthy, works out and ends up looking great…that’s not vanity. The person that knows that spare tire or extra 20 lbs. is not healthy and wants to remove it (them)…that’s not vanity. A person who wants to look “acceptable” or “presentable” to attract a mate…that can be borderline, again depending on how far past looking one’s best they take it and intend to go.
