What's an ab? I couldn't find an explanation or translation.
Is it another term for body fat?
Some of the boys I went to school with or now study with are very extreme with it. Gym nearly daily, supplements to the food, and they even plan what to eat when, what quantity, and so on.
I love my freedom to eat what I want when I want it
I could never make a plan for the week when it must be fish, pasta, meat, and so on.
But this aim to have the perfect body started back in the late 60s, 70s, and that was when the modern feminist movement was at its beginning. I don't think there is much influence from women.
Besides, men have tried to be attractive to women long before the first women started to claim their own rights.
Now the media might get confused at timeshow to portray the genders, and I think one reason is that some of the classic gender roles now aren't fitting that well anymore. So the media finds it difficult to portray men and women outside of the classical gender roles, is adjusting, and sometimes shoots over the top.
On the other hand men are now more secure in showing a somewhat feminine side, and women a masculine.
In most countries the media is still controlled by men, with the top positions very rarely represented by women, so I would not agree with any change in the media representation due to a feminist pressure.
As Angela Harlem said, and I think you have to be blind not to see it, neither men nor women are very positively portrayed in sitcoms or cartoons.
