Actress Millie Bobby Brown jiggles her flabby ass flaps while jogging down the beach in a thong bikini in the video above.

As we can see from Millie’s doughy, cellulite-pocked body and that awkward, wheezing running form, she is not used to this type of physical exertion… While the photos above clearly illustrate where the majority of her muscle memory lies.
Yes, if Millie truly wants to undulate her sloppy booty meat and bounce her breasts, she should do so while performing the one activity she has mastered (and it sure as hell isn’t cardio).

For as we can see from Millie’s swollen labia bulge, she only ever “works out” one part of her body…

And she is always on the lookout for a new training partner to push her to her limits.
