The Keeping Up With the Kardashians star put her booty on display in a seriously sexy swimsuit that she wore while demonstrating her stretching routine.
The post was appropriately titled: "All about that bass, get acquainted with my St. Barths booty."
"There's no such thing as a vacation from fitness, so I made sure to schedule in a workout during my St. Barths getaway last month," Khloe wrote. "I went for a run in my bathing suit and Nikes, but while I was stretching, Joyce Bonelli (my makeup artist/BFF) and Hrush (my Armenian goddess makeup artist), kept urging me to do a little photo shoot and they just started snapping away lol.”

We have to assume that the accessories were added for the impromptu photos. Who would want to run in hoop earrings?!
Khloe admitted that she loved the photo shoot, adding, "Just a five minute shoot but I got way, way into it!"
ET spoke with Khloe's personal trainer Gunnar Peterson who said that her body transformation is all due to good old fashioned "hard work."
"This is Khloe's moment," he stressed. "You can see it. The changes she's made are incredible. She's done it the right way. Nothing fast -- hard work. It's steady, hard work and it's very relatable and her body is banging right now."
