Why are some girls jigglier than others?

Definitely agree about the amount of muscle vs. fat thing.  From this view you can’t even see where most of her weight went (her beer belly) but this shows a part of her gain that she’s in more denial about - her ass.  Even though it hasn’t really grown in size like her belly has, it’s completely changed in texture—it never would have jiggled this freely with such a small movement back in her athletic days. No muscle tone left.
