Halle Berry's Hot Body Secrets

Halle Berry's Hot Body Secrets Revealed!. Halle Berry just keeps getting hotter.

At 46, the Cloud Atlas actress and mom to 4-year-old Nahla still has one of the most enviable bodies in Hollywood.

"Halle's body looks 10 years younger, at least," trainer Nat Bardonnet told Us of the star's taut tummy and long, lean legs. "She's an inspiration!"

Some of that, of course, is just good genes. But as Bardonnet revealed in the Oct. 29 issue of Us Weekly, Berry also works hard for her body. The busy actress sweats it out with the pro four days a week in hourlong sessions that include squats, leg raises, lunges, and pushups.

Recently, the hot bride-to-be -- she and French actor Olivier Martinez announced their engagement in April -- has also been boosting her routine with a combination of cardio and weights.

"For the past two and a half months, she's been doing very intense, 30-minute cross-training workouts to shock her body," Bardonnet told Us. "It's responding well!"

Indeed it is. But health starts from the inside out, so to fuel up between sweat sessions and keep her metabolism in check, Berry chows down on five small meals a day -- often salads, fish, and soups.

"Cardio is important but nutrition is key," Bardonnet advised. "To look like [Halle], cut sugar, flour, and cheese to twice a week."
