Summer might be over, but that doesn't mean you should be lazy with your workouts now that it's the fall season (after all, leather pants are one of the biggest fashion trends).

Celebs are some of the best folks at staying in shape, thanks to their highly demanding schedules, multiple red carpet appearances and photo shoots that often require showing off some serious skin (plus the occasional trainer and nutritionist to help).  

From Cameron Diaz to Gwen Stefani to Miley Cyrus, Hollywood babes of all ages love to bear their washboard abs and are constantly hitting the gym, the Pilates studio or even the beach in order to stay in perfect shape.

And, of course, you've got your abtastic hunks like Ryan Gosling, Matthew McConaughey and Jake Gyllenhaal, who love to work out shirtless, show off their bulging biceps and always make us swoon while they sweat.

But remember, working out isn't just about having a bangin' bod, it also keeps your heart healthy, enhances your mood and helps with weight management as we prepare to indulge during the holiday season.

So, with these super-fit stars as your inspiration, hop on the treadmill, pick up a dumbbell and start sweatin' it out.

Then, be sure to schedule a photo appearance to show off your fabulously fit-and-trim figure!
