Teresa Giudice
The Real Housewife may have found yoga during her 11 months in prison (better than anything else she could've picked up) but after her release, turned to something else: bodybuilding. In fact, she became such a dedicated lifter she entered a competition and placed third.
These drastic transformations from Real Housewives will blow your mind.

Khloe Kardashian
There's a reason she hosted a show called Revenge Body. After splitting with first husband Lamar Odom, the gym became her "only refuge." And while she found — and lost — love again (though, this time, her daughter True came from her lousy split from lousy Tristan Thompson), she continues to focus on herself and is a testament that breakups aren't always a bad thing.

Chris Pratt
Before Guardians of the Galaxy, actor Chris Pratt had a totally different look. To prepare for his new part, he dropped 60 pounds to play Star Lord, both from exercise and a drastic change in his eating. There's something about these Marvel movies that get actors to get in tip-top shape.

Jennifer Garner
Jennifer Garner has never really not been in shape — but shortly after marrying Ben Affleck, she settled into motherhood, cut back on her acting career and raised their three kids and didn't prioritize the Hollywood standard as much. But when Jen and Ben split, she got a new lease on life. Yes, she's still an awesome mom who is always there for her kids but she also returned to the industry and headlined the action movie, Peppermint, in a physically demanding role that got her back to Alias fighting form.

Christina Aguilera
Several years ago, Xtina found herself in a bit of a funk but when the mom of two discovered the "love and good energy" yoga provides — she downward dogged right into it, practicing as much as five times a week for one-to-two hours a session.

Gal Godot
To become Wonder Woman, Gadot had to bulk up — which meant preparing for the role was "more intense" than her time in the Israeli army. Yowza.

Drake
You may love Drake's music but never thought of him as anything but a chart-topping rapper. Nowadays, however, he's shaping himself up to be as hot as his songs, just by doing the things you're supposed do when you want to fill out the right way: exercise (weight training and playing basketball are his go-tos) and healthier eating (cutting down on pasta and alcohol).

Nicole Polizzi
After being called a meatball for so long, the gal formerly known (or still known) as Snooki decided enough was enough. After having her first child, she hit the gym hard and never looked back — even as she is currently pregnant with her third.

Candace Cameron Bure
Candace Bure's run on Dancing With the Stars changed her body, and the Fuller House star capitalized on her new fitness by continuing to strengthen and tone. But not with dance; rather, she heads to the gym or her trainer does a session with her on set.

Nick Jonas
Nick went from boy to man (man-boy?) after breaking out of the family music group and going solo. But now that they've reunited, don't think Nick is going to revert back to his former image — especially if he wants to hang on to Priyanka Chopra.

Miley Cyrus
Soon after leaving Disney and meeting now ex-husband Liam Hemsworth in that Nicholas Sparks book-turned-movie, Miley found yoga and exercise and combined with all that twerking (also a thing of the past), she left Hannah Montana in the dust and replaced her with a healthier, less wild adult.

Kevin Hart
Hart was always one of those guys who looked to be in decent shape but managed to hide it well. He told
Men's Journal
that in 2016, he wanted to be a man who could take his shirt off and be happy with what he was showing off. So if that meant busting his butt at the gym, trying to match up to his BFF/mortal enemy Dwayne "The Rock" Johnson, so be it.

And while she's always been a fighter, she's literally become a beast in the ring, even knocking out a dude's tooth. Don't mess.

Carrie Underwood
The singer works out a lot — though, admittedly, it's a little harder now that she has two kids. That being said, even if it's a quick workout, it's better than nothing.
