Maybe the OP stepped inside a gym and was surprised that TV and movies are wrong.

I like to think so, yes.

Well, we see someone with a MLP avatar come in and ask us whether we think it's weird to see a woman lifting weights.

My sarcastic answer would be: "No weirder than a guy watching a TV show made for little girls" (and remember, I'm a brony myself).

But my real answer would be that it is culture that predominantly shapes our conceptions about what is and is not male / female "responsibility". There is nothing weird about a woman lifting weights aside from what the culture tries to ram down our throats about what is "male stuff" and what is "female stuff". Typical stereotypes.

I mean, no disrespect I like ponies about as much as the next [censored] but this is just a little ironic no?

There has been three remarks already so I think it's safe to say that we're well aware of the irony and cognitive dissonance.

Most of the nurses at the hospital I work at go to the gym. My aunt does Zumba Fitness (whatever that is).

Boom goes the dynamite ! It's fun watching these blow up. Please continue

Well excuse me.

I... well, little topic starter, one day you will go out in the wider world. Take a notebook. Apparently a lot of things will surprise or amaze you. For example, did you know women got the vote like a hundred years ago. And... we drive 'n stuff? And some of us are the primary breadwinners in households. Some even *gasp* like sports! Get out! Shocking, amirite? Oh, and sometimes we're wicked sarcastic too.

Honestly, there isn't a lot of discussion going on here. And I don't think the professed surprise at seeing a woman lifting weight in a gym, which is neither surprising or unusual regardless of the region of the country you live in, is much of a a useful discussion point for gender equality.
