I consider them one-and-the-same. not much of a difference between a fitness and bikini model. They look like clones.
Yep, always the same BS, in the beginning you had attractive female BB, then these turned into freaks so they invented "fitness girls", when these strted to turn into freaks or got too old, they invented "bikini girls", they are what fitness was 10 years ago.
In ten years, you will have something else because the bikini girls are all roided out freaks.
