Robert Pattinson

Zoe Saldana


Zoe Saldana opened up about her approach to wellness in an interview with Shape. "I can't work out regularly, so I compensate by eating a lot healthier than I might otherwise," she explains. "Once you have relatively healthy eating habits, your workout can become playing with your kids, strolling around the neighbourhood, playing airplane, or just changing diapers."


Emily Blunt


Emily Blunt shared one of her biggest wellness hacks with Glamour. "I would say if you feel yourself coming down with a cold, which I'm like the worst person to nominate this because I sound horrible today – tail end of laryngitis. But… oil of oregano. You sort of just throw a few drops down there. It's disgusting, you burn your throat but I do tend to find it shortens the cold."


Chris Pine


Chris Pine opened up about his life and career to Men's Journal. He says that he has reached a point of comfort in his career.  "I realized after Star Trek that I'd achieved a lot, I was financially independent; but something about my way of going about life wasn't satisfying me. So I made a decision that my main objective is to be happier, as opposed to more successful. That's what I want."


Harrison Ford


In an interview with Esquire, Harrison Ford opened up about what he's learned in life. "We look for ourselves, and we look for useful information to help us navigate our fucking lives and the world that we're living in," he says. "We don't realize we're looking for that. But we're looking to pull out of a fantasy something that's useful to us. And what's useful to us is to emotionally participate in things outside of our own lives."


Matt Damon


Matt Damon's trainer, Jason Walsh, opened up about how the actor got in shape to Thrillist. Damon was a fan of using the VersaClimber. "On the VersaClimber, he would end up averaging 4,000ft or 4,500ft, which we would do in 30 minutes. Which is really, really good. That's a lot of work in a very, very short amount of time."


Jude Law


Jude Law works with trainer, Johnny Silmon, to help him stay in shape. "Jude always puts a good shift in," Silmon tells Men's Journal. In addition to their five sessions a week, Law does an additional two or three on his own.

If you are going to be picking people up over your head, you had better be pretty strong."


Jake Gyllenhaal


In an interview with TODAY, Jake Gyllenhaal opened up about how he got into eating a plant based diet. "My father was already healthy going up and trying different things. he was the first person to introduce me to soy milk. He cooked things with tofu.

Milla Jovovich


Milla Jovovich opened up about her diet in an interview with People. She says that she makes sure that her way of eating is sustainable, and shared her approach. "To be honest, I just found that making sure that 80 percent of my diet during the week is vegetable-based and everything else is just smaller portions, helped my skin, helped my energy levels, just helped everything."


Adam Driver


Adam Driver works with trainer, Simon Waterson, to help him stay in shape for the Star Wars movies. He shared some of Driver's workouts and approach to fitness with Men's Journal. "These workouts were all about the tempo and transitions," says Waterson. "The movements should be fluid, like one continuous exercise without sacrificing form."

"If I can't bring anything to it, I'm not going to go and be involved in it," he says. "I don't want to do that again. I don't want to just be the action figure standing in the front. And that's OK. It takes a lot to understand what you do want from this industry." 


Sandra Bullock


Sandra Bullock's facialist, Georgia Louise, talked about the actress' skincare routine to People.  "I wanted to give [Bullock] something that would transform her skin without the need to undergo lasers, so I loaded up her bespoke facial with something that would give her long-lasting results.
