OK! magazine reveals your favorite celebrities’ best-kept workout secrets—and what the stars do to stay so fit!

Khloe Kardashian, who seems to live at the gym, is as dedicated as we all think! “She comes in every day between 6 and 10 AM. Her boxing skills are exceptional,” trainer Gunnar Peterson told OK!

And while it’s been tough for Rob Kardashian recently, his recent weight gain is “just a blip on the radar,” Gunnar said. “He’s back on his path — and his work ethic is second to none.”

Jennifer Aniston does yoga to keep fit but the one thing that does not fit in her workout routine? Clothes! “Jen prefers to do a yoga workout first thing in the morning while naked.” a source told OK! “She believes clothes get in the way of doing the poses properly.”

Speaking of sexy workouts, Lea Michele’s choice of routine is: pole dancing! “Lea’s totally into pole dancing classes and has confessed that she fantasizes about being a stripper,” a source said. “She gets into it and makes sexy faces!”

Shia LeBeouf is just as intense at the gym as he is in real life, a source said. “Shia makes such loud grunting and yelling sounds at the gym. Clients complain that it’s like he’s having an orgasm!”

Reese Witherspoon, on the other hand, isn’t a fan! “I work out for my job,” the actress told OK!, “but it’s not my first choice of activities. If I never had to see the inside of a gym again, I’d be a happy person.” No wonder she's so happy in this photo--she was leaving!

Meanwhile, Ariana Grande “works out hard and is a sweaty mess afterward.”
