Jennifer Aniston used to ''beat'' herself up about the way she looked.

The 'Cake' star believes she took an ''unnecessary'' disliking to her figure when she was younger but has since learned to love her body whatever shape she's in.

She told The Huffington Post newspaper: ''When I was younger, I think I took a lot for granted and would beat myself up over things that were unnecessary.

''Now it's like, whatever state I'm in, whatever shape my body's in [works for me]. I think you just have to really appreciate that this is what's beautiful, this is you!''

Despite her globetrotting schedule, the 46-year-old actress will always find time to work out whilst on set.

She said: ''I will bring a DVD of something like my friend Mandy Ingber's yoga or Cardio Barre, where I hold onto a chair and do the moves.

''I might bring [resistance] bands, which I put on my legs around my knees and do different leg exercises. Or I might find a great gym wherever I am. I am a runner, but sadly right now have a hip injury.''

Jennifer also admitted she prefers working out alone so she can ''get in the zone'' but doesn't mind holding classes at her home for her girlfriends.

She added: ''I love the energy of a class. I have a great [home] gym with a ballet barre and will sometimes have two or three girlfriends come over and do a class, that's fun.

''But mostly, I pretty much like to be left alone, put my earphones on, and get in the zone.''
