At only 22, Jen Selter is taking the fitness world by storm. She is signed with The Legacy Agency, a huge sports agency that represents baseball stars Carl Crawford and Johan Santana, NFL players Osi Umenyiora and Reggie Bush, and sports Broadcasters Troy Aikman and Dan Hicks. Her agent Andrew Witlieb has been quoted as saying that Jen has the potential to become “the next Jillian Michaels,” which is high praise for young model. Jillian Michaels, trainer and judge for NBC’s The Biggest Loser is a huge success with an ever-growing number of endorsements and appearances. Jen’s agency is excited for her career, saying she’s “going to grow as a person and a fitness expert … She’s here for the long term.”

The fit and curvy Long Island native first made her appearance on Instagram in March 2012 when she started taking photos of herself working out at the gym. Today, she has nearly ten million followers on Instagram (including 2013 Heisman Trophy winner Johnny Manziel, Amar’e Stoudemire, and Shaquille O’Neal), over 24 million followers across her other social media channels, and is starting her own fitness empire.

Without a doubt, Jen is most famous for her “belifes,” or, butt selfies with over 380 of them posted on her Instagram page. She even taught Barbara Walters the art of the belfie when she taped an episode of The View. On Jen’s segment, she confirmed that her butt is real and got the cast of The View to break a sweat while performing a routine of squats and donkey kicks.

In addition to her appearance on the view, Jen has appeared in Elle, FHM, Muscle & Fitness, Vanity Fair, and Maxim magazines. She has also made television appearances on Access Hollywood and Bethenny. In 2014, she was voted 82nd in the top 99 Most Desirable Women 2014 by AskMen.

In a feature with BodyBuilder.com, Jen tells readers what she does to maintain her infamous rear end. Her favorite booty workouts include donkey kicks, fire hydrants, chair kicks, squat pulses, squat kicks, and using the Stairmaster or treadmill at a steep incline.

No matter how tired she is, Jen never shies away from gym time and works out as much as four hours after work each day. After high school, Jen dabbled in cosmetology, worked in a doctor’s office, and at a gym before settling into her current career. Her ultimate goal is to inspire people to be their best selves. On her website, JenSelter.com, she offers her fans the opportunity to take place in the #JenSetlerChallenge – a free thirty day challenge that helps “kick-start your fitness, inspire you to begin a routine to help get you into the best shape for summer.” The challenge features three to four workouts a week and two days of cardio.

Jen and her rock-solid bod are highly in-demand with endorsement deals from companies like Calvin Klein and has been featured on the Tumblr account “Girls in Calvin Klein Underwear.”

She may be a social media star, but this fitness model is as authentic as they come. Her commitment to advocating for fitness, a healthy lifestyle is not just about bettering herself, but helping her fans reach their goals as well. Her career is just getting started, but there are no doubt more endorsement deals and fitness
