Lara Croft is the female equivalent of Indiana Jones, and he definitely doesn't have a gut till, like the fourth movie. They are extremely fit.
So are a bunch of other characters pictured here. Assassins, martial artists, etc. You generally have to be fit to be competent tat these things, and being competent at these things makes you fit.
It would seem we agree my fine fellow. ObiWan and Shinobi were both fit as well ;)
