Why don't girls look at hot shirtless guys when they are out running for exercise?

When I walk around my park nearby, I've noticed that if there's a good-looking, shirtless, muscular (but not too muscular) guy running around, the girls that may be out walking or whatever don't check them out or even look at them. What's the reason for this? Are all the females that say females are visually-stimulated too, lying?

Not many answers unfortunately, but seems like when girls say that they're visually-stimulated too in terms of sexuality, as much as males are, they're either dumb or lying.
