Similar tags, and yet not totally alike, I know ... yet are they similar enough to do away with one of them?
#1 reason I am submit this: the frequent misuse of the toned tag to describe huge, bulky, ripped-to-shreds 'roid-monsters, and by more than a few users.
These posts should be tagged with big_muscles.
Please refer to the toned wiki.
Between the two, I would always search athletic for the body-type I am looking for, yet this is a personal preference, I know.
In short, you rarely have athletic without being toned, yet it is not uncommon to be toned by virtue of being a gym-rat, while not particularly athletic.
