Jen Selter Shows Off Athletic Torso In Purple Sports Bra

On Monday, the 21-year-old celebrity posted a photo of herself on Instagram where she rests on a giant white bed wearing a small white top and short purple bottoms. As she lies face down, the majority of her body looks flat- except of course in her backside, which sticks out completely.

Selter has here eyes closed and looks pretty peaceful as she rests next to a healthy exercise product.

In a previous interview with The Huffington Post, she revealed the main thing that keeps her going in life, which can be helpful for everyone else.

"My ultimate beauty tip I can share with people is to drink water," the exercise model said. "Drinking water is extremely helpful across the board. Making sure you are hydrated is especially beneficial in terms of skin, it will help with any dryness one may experience."
