It's no wonder she has such an incredible body to show for all that hard work.

Jennifer Aniston loves working out and has dreams of opening her own wellness center. But she's also absent from social media (other than lurking on Instagram), so you won't catch her posting gym clips. Needless to say, you're not alone for wondering just how she sweats to get and stay in such incredible shape. So we jumped at the chance to chat with her trainer Leyon Azubuike to get the deets on her current training.

First, Aniston is as much of a beast during workouts as you'd expect. "Anything I throw her way, she brilliantly attacks it to the best of her abilities," says Azubuike. "She's always receptive and open to trying new things and learning new techniques as we work out."

And she's committed: She typically trains three to six times a week for 45 minutes up to two hours. She'll train longer and harder when an event is in the distant future and then scale back when it's right around the corner. The workouts themselves are constantly changing. "We love to work the whole body, and we love to incorporate the resistance bands, jump ropes, a variety of routines that work the core," he says. "We love to box. Jen, she loves boxing." In addition to boxing drills, Aniston particularly enjoys using resistance bands, says Azubuike. (Related: The Best Total-Body Exercises to Try with Every Kind of Resistance Band)

There's a reason that Aniston seems like the 300th celeb you've heard of who is a boxing devotee. (See: Celebrities Who Have Boxed Their Way to Fit Bods) It stands out among other workouts for its physical and mental benefits. In addition to being good for your strength and cardiovascular health and toning the whole body, it works your mind, says Azubuike. "The release that you can gain from boxing is something that I think is very attractive about the workout," says the trainer. Aniston is clearly here for that release: "You get a mental release of all this crap you're taking into your ears and eyes every day and have little fantasy moments imagining who you're punching," the actress previously told InStyle.

If you want to get in on the action, Azubuike suggests a few drills you can try at home. Even just holding a basic boxer stance-feet about shoulder-width apart, non-dominant foot in front, fists guarding your chin, knees slightly bent-can be a challenge. "You'll see that your core is engaged and your arms will start to fatigue, and the glutes, hamstrings, and calves start to burn," says Azubuike. From there, you can progress into jab crosses (a straight punch with your front arm, followed by a straight cross punch with your back arm) holding 2-pound dumbbells. "Just start with the basic one-two while you're rotating across your body and seeing how that benefits the torso, the core, and your arms." A few or Azubuike's crucial form tips: Guard your chin at all time. Make sure to turn your knuckles over so they're horizontal with each punch. Keep your elbows in.

But even if you still have no interest in boxing, you can still train like Aniston by keeping your workouts dynamic. "She's constantly finding new ways to engage her mind and body in order to stay at and top her game," says Azubuike. Consistently working out and switching up your exercises to encourage muscle confusion are key, he says. With that in mind, here are 20 ways to bust out of a workout rut.
