Fortunately, I haven’t really heard this directed towards me personally. What I have heard though is other women say they don’t want to get too big, too bulky, and I think it’s because of stuff like this!
If someone is consistently working out, if they’re trying their best to improve themselves, then other people’s opinions are irrelevant. We all have different body shapes, and we all have different goals. You don’t get a say in that. You don’t get to determine how other people “should” look, and you don’t need to comment.
