Charlotte McKinney’s Crazy Butt Workout Isn’t Just For Any Bum [VIDEO]

Charlotte McKinney works out her butt like no one else.

The swimsuit model — and only reason anyone eats at Carl’s Jr.’s — posted a video of her workout routine on Instagram Thursday and it’s quite impressive.

“Thanks for always kicking my bum,” McKinney captioned it.
