Jennifer Aniston and Courteney Cox are said to have dieted and exercised vigorously before their Mexico vacation.
The Friends actresses jetted to Mexico for New Year's with a group of friends, including 44-year-old Jennifer's fiancé Justin Theroux and funny man Jimmy Kimmel.
Making sure they looked fabulous in their bikinis on the beach the two pals are said to have undergone a strict diet before their trip.
"Before they went away, Jen and Courteney did a five-day detox juice cleanse that included five veg juices a day and one protein shake with vanilla bean and raw cacao," a source told British magazine Closer.
"Every day they did an hour of Pilates followed by a four-mile beach run. They even had a session in a special sauna pod in LA, which uses infrared technology to reduce bloating."
Even while on holiday Jennifer and Courteney reportedly continued their healthy eating and intense work outs. With their stunning vacation spot came a professional chef to whip up some tasty and nutritious meals for them.
"They started their days with beach runs and 30 minutes of toning exercises, while the private chef at their luxury villa prepared low-carb, sugar-free meals for them," the insider added.
The pair were rumoured to have had a rift in the past, which was sparked by 49-year-old Courteney's absence at Justin's 42nd birthday party last August thrown by Jennifer.
However they are said to be closer than ever now and Jennifer is said to be grateful for her brunette friend's support while Justin worked in New York.
"Jen credits Courteney with supporting her through a lonely few months without Justin - she says she's kept her 'sane'," the insider said.
