Teen Mom 2's Kailyn Lowry is all up in the club workin' on her fitness! This gal has been struggling with her extra baby weight for the past couple years, and she's ready to drop a few pounds — even though she's completely comfortable with her curves.

Kailyn got super fit back in Summer 2012 thanks to the Insanity program, but she gained most of the weight back once she stopped working out. As we all know, this gal looks picture perfect at any size (and let's get real, she's pretty tiny), but she's currently on a workout kick in anticipation of seeing her husband, Javi Marroquin, for the first time in three months!

"Trying to get back to this," Kailyn posted to Instagram on February 7 along with a picture of herself and Jo Rivera at prom. "#lacross #insanity #fit."

Wow, Kailyn was so petite! But it's natural that her body has grown and changed since high school, so let's hope girlfriend doesn't beat herself up over getting back to her pre-baby shape!
