The busy mother of four shows off her bikini body and also reveals to the magazine how she manages to stay in such great shape year-round. "I try to get to a Pilates Plus class, which is an intense, fast-paced workout that's done on a special reformer machine, at least three times a week. I also go to the gym a couple of times." She explains that she spends 15 minutes on the treadmill and also completes a 45-minute head-to-toe workout she designed with trainer Gregory Joujon-Roche for a DVD.

Brooke says getting the right amount of sleep is also important, but can be challenging because her two youngest kids usually end up in her bed at some point during the night. She does try to get a full eight hours of sleep at least one night a week and reveals that she and David sometimes even take "sleepcations," where they check into a hotel room just to be alone and sleep. On balancing sleep and sex Brooke says: "I'm so sleep deprived! How can I possibly choose between those two? That's really tough. Can't I sleep after the sex?"

Brooke is on her second marriage and said that her current husband, former Baywatch star David Charvet, is truly her "soul mate." For Brooke's full interview and photo spread, pick up a copy of the January issue of Fitness magazine, on newsstands December 20th.
