As someone who writes some fiction and is working on a story idea involving competitive women, the fighting over a man thing seems almost a cliche.
The story idea involves a pair of well-matched physique competitors/fitness models, i.e., who compete body to body, muscle to muscle in a unique, classy setting before a select audience, some of whom may bet on the outcome. Each has an elegance and style all her own, but is still strong and competitive.
I'd love to hear from the competitors here (and fans, too): What might prompt a woman to challenge another (or accept an invitation to compete in this situation). Money? Some kind of prize? A lucrative modeling job? Pride in proving her physique is superior without the verdict of judges?
Or is it really a guy after all?
