Jennifer Aniston is "much gentler" on her body nowadays.

The 56-year-old actress feels she now understands her body better than ever, and Jennifer has become "smarter" with her workout routines.

The Hollywood star told People: "You have to really honour where your body is, which I've gotten so much better at as I've gotten older."

Jennifer observed that "strength training has made the biggest difference" to how she looks and feels about her body.

The actress reflected: "As I've become more educated about the body over the years, I've been able to become stronger than I'd ever thought."

Jennifer's trainer, Dani Coleman, has taught her some important workout lessons, too.

The movie star said: "I used to think a workout meant you just got to sweat for an hour to 45 minutes, whether it's running around a room, doing aerobics or running on a treadmill - 45 minutes of cardio. Otherwise, it's useless. I'm just so grateful that's not true."

Meanwhile, Jennifer is one of the biggest names in Hollywood - but she previously confessed to being terrible at auditions.

The actress admitted that she struggles to find immediate chemistry with a stranger, and so she rarely excels during auditions for parts.

Appearing on The Hollywood Reporter's Drama Actress Roundtable - which also featured Nicole Kidman, Jodie Foster, Sofia Vegara, Brie Larson, Naomi Watts and Anna Sawai - Jennifer said: "When you're in an audition room, you're already at a disadvantage. Maybe you'd have chemistry with this person if you were in a different environment, and not, like, 'Create chemistry. Ready? Go!'

"And I'm a terrible auditioner, always was. I waitressed forever before I could finally get something, which was a Bob's Big Boy commercial."

Jennifer also insisted that she would never get intimate with an actor during a chemistry test.

The actress - who is perhaps best known for playing Rachel Green in Friends - said: "I haven't been told you're going to have to lay down and [get intimate with an actor for a chemistry test], and if asked, I would never."
