JENNIFER ANISTON - HOW ANISTON GOT IN SHAPE

JENNIFER ANISTON got in shape for her Vanity Fair covershoot thanks to her former FRIENDS co-star COURTENEY COX and a custom-made holistic exercise technique.

Cox told Aniston about Budokon, which was developed by lifestyle coach CAMERON SHAYNE in 2002.

Shayne - who describes himself as a martial arts master, yoga teacher and lifestyle coach - explains Budokon, "By exploring the physical, emotional and spiritual body through movement, diet and meditation, the student works toward achieving truly sustainable health, wellness and personal power."

He adds of Aniston, "She started with me last summer. But she's a busy woman so she tries to get in when she's in town.

"Because Jen's very laid back. It's good for her to get some of that fire energy out."

Shayne's other celebrity clients include MEG RYAN, KRISTIN DAVIS and RENE RUSSO.
