Let's face it, the eternal struggle that is motivating yourself to exercise is a tale as old as time. Somehow, though, a few celebrities seem to have squashed the urge to skip the gym in favor of the couch, and it's sure as hell paid off.
Whether it's to prepare for physically challenging roles or because they chose to focus more on their health, these celebs prioritized fitness and completely transformed their bodies. One even became an acrobat—so there's that.
If you're the type of person who's always promising to "start tomorrow," look no further because this is all the fitspo you'll ever need.
A peek at Kourtney's Instagram will reveal how just much her almost-daily 45-minute workouts have paid off. The mom of three sculpted and strengthened her abs with burpees, mountain climbers, and jump rope—and still keeps up her badass routine.
For the film, Peppermint, Jennifer had to get in insane shape for her physically demanding role and now she's got the arms to prove it. Like her character, who bulks up to avenge the deaths of her husband and daughter, Jennifer saw results through serious dedication to her workouts. The actress paired up with trainer Simone De La Rue, and even documented some of their routines on Instagram.
At 18, Demi checked into rehab to get help for an eating disorder, substance abuse, and self-harm, per People. Fast-forward eight years: The singer and actress built a strong body with the help of her gym, which she calls her oasis.
These days, she alternates between mixed martial arts and weight-lifting, which she does six times a week.
Miranda built an even more fit figure thanks to her trainer, Bill Crutchfield. For top results, he mixed up her routines. "I think variety keeps you mentally fresh and also helps you physically respond better," he told Women's Health.
To keep her body toned, Miranda uses exercise bands, she jumps rope, and boxes.
When Xtina decided she was going take better care of herself, she turned to yoga. "Healthy is a state of mind, and it has to come from inside. It is not a situp; it's not a calorie count—I hate that," she told Women's Health. Molding a new physique was not her goal, but after one-to-two hour sessions five days a week, it happened anyway.
