Aniston meets with Mandy Ingber, personal trainer/yoga guru, three times a week for hour-long private sessions. By mixing cardio and yoga, Ingber’s technique is responsible for Aniston’s tight butt, toned legs, and ripped abs.

Although Ingber says her rates are confidential, author of “Celebrity Personal Trainers,” Scott White, says many celebrity trainers charge upwards of $300 an hour. Using this estimate, Aniston’s weekly fitness costs would be about $900.

Do-it-yourself tip: Look for deals for yoga classes on sites like Living Social and Groupon to get your first 10 classes cheap. If you’d rather work out with Ingber, you can purchase her DVD for only $14.95 and train in the comfort of your own home. Looking for an easier way to look as good as Aniston?
