Mackenzie Douthit is a miracle of science, you guys. This girl gave birth to her second child back in February, and currently is wandering around Oklahoma with a six pack. Sigh, we don't know how she does it.

Mackenzie actually weighs less now than she did before her second pregnancy, but even she has insecurities! Thanks to her grueling workout routine and life as a professional cheerleader, Mackenzie has huge biceps and triceps, and she's worried that  they make her look a bit on the buff side.

"I have came to the conclusion that my arms will never look like woman arms...." Mackenzie tweeted on June 23. "They seriously belong on a man."

Psh, no way! Women should be able to own their muscles just like men do, and Mackenzie's guns don't make her any less feminine. In fact, this southern belle is about as girly as a gal can get!

Sure, her arms are way more muscular than those of the dude holding her up in this stunting picture, but she looks ah-mazing! If there's one thing we've learned watching Teen Mom, it's that beauty comes in all shapes and sizes.

Do you think Mackenzie's arms "belong on a man"? Head to the comments!
