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.

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.
