Jen Selter Dons Naughty Bathing Suit On Instagram

On Monday, the model posted the pic on Instagram where she dons a black top with light blue shorts that display her muscular figure. As she raises her arms, her flexed muscles can be seen in her tummy that looks hard as a rock. She also flaunts her shapely legs that she works  extremely hard on.

In the caption, Selter mentioned how keeping in shape should be a way of feeling better instead of relying on unhealthy food.

Jen Selter Reveals 'How Far' She's Gotten

"Let exercise be your stress reliever, not junk food! #MotivationMonday," the caption reads.

Selter might be known for her washboard stomach and strong thighs, but it's her backside that makes her the icon she is today. Ever since her behind started looking mighty thick, she eventually became one of the most popular celebrities who soared her way onto social media.

In an interview with The Huffington Post last year, the 21-year-old talked revealed one of the most important ways to feel refreshingly beautiful.

"My ultimate beauty tip I can share with people is to drink water," she 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. In New York this is often a problem especially during the colder months!"
