Chelsea Houska Bikini Body: 'Teen Mom 2' Star Debuts Weight Loss In Two-Piece Swimsuit

Chelsea Houska recently debuted her swimsuit body -- and she's looking great.

In a new photo posted to Instagram, the Teen Mom 2 star is looking trimmer than she's ever been, and according to a source, Houska's slender bikini body is the result of her hard work at the gym.

"Chelsea goes to the gym 4-5 times a week,” a friend of Houska's told Radar Online on June 30. "She loves kickboxing, cardio and weight-lifting."

Since breaking up with her daughter's father, Adam Lind, Houska has been focused on her fitness and just last year, vowed to get into better shape. Although Houska admitted to letting herself go a bit after her and Lind's breakup, she is now in a much healthier place, both with her body and with her mind.

Not only has Houska ditched pizza and opted to replace it with healthier foods, such as fruits and vegetables, she's also been taking group classes at Kosama fitness center in Sioux Falls, S.D.

“Chelsea makes nutritious meals for herself and Aubree,” the insider explained. “She makes veggie juice every morning. Aubree loves her broccoli!”

Lind, on the other hand, isn't doing so well.

In addition to a breakup from his second child's mother, Taylor Halbur, in mid-May, Lind was recently arrested after breaking the rules of the 24/7 Program he was placed on, following his third DUI. The program is a system in which DUI offenders undergo drug and alcohol testing once a day. Thus far, it has not been revealed whether Lind didn’t show up for testing or tested positive for alcohol.
