"Masculine"? "Hulk Aspen"? ...You guys are funny. It's not as if she put on 20lbs of muscle; she mostly just got toned and lean(er) (I recall her saying she'd lost weight, at least at one point in the process). I thought she actually looked pretty good, though I don't know if I'd go as far as "better". She did add some nice shape to her ass that she didn't have before... If nothing else, I admire the effort she put in.
Her problem is that she has a short, fairly square-ish body with A-cup boobs (cute as they may be). It just makes any little change really stand out. There was a period, a couple of years ago, when she let herself get a bit out of shape - at least by her standards. She probably gained no more than 10 lbs, but on that body, it really showed. Much like that previous weight gain would've probably gone unnoticed, I'm pretty sure that if she had boobs and hips and an hourglass waist, nobody would be here sweating a little extra muscle in her back and shoulders either.
