Briana Dejesus is ready to kick those pesky pregnancy pounds to the curb! This Teen Mom 3 starlet packed on quite a bit of weight to her slim physique while pregnant with her daughter, Nova Star, and she wants to get back to her old self, y'all. Briana's lost most of the extra poundage she put on during pregnancy, but apparently she wants to look even more amazing (if possible) and she's turned to Insanity for help.

"Mom got us the insanity workout!" Briana tweeted on September 15. "Time to get back on track & get fit!"

According to Insanity's website, the workout involves "maximum-intensity exercises with short periods of rest."

Yikes, sounds insanely intense! If Briana follows the program to a T, she could burn 1,000 calories in just an hour — which means she can eat all the pizza she wants! Or diet. Either way.

So, how was Bri's first day of Insanity? Rough, guys. Rough.

"Just did my 1st day of insanity work out!!!" she tweeted. "Never sweated so much in my entire life and it was only a warm up OMG HOLY S—."

Briana isn't the first member of the Teen Mom Mafia to workout with Insanity. Kailyn Lowry used the 60-day program back in spring 2012 and had amazing results! Of course, both these ladies look drop-dead gorgeous at any weight, but hey — a little exercise never hurt anyone. And when we say "a little exercise" we actually mean a grueling workout routine that renders most people immobile.

Now excuse us while we go order some hot wings.
