April 28 was just another day in Britney Spears' healthy new life. The star, who has recently swapped fast-food runs for daily workouts, hit her regular Bally Total Fitness facility in Studio City, Calif., for an hour-long Spinning class. After the session, Britney stopped to chat with Life & Style. "I'm always happy when I'm done," she said, before offering some one-on-one insight into her favorite cardio workout - hitting the dance floor. "To me, dancing doesn't even feel like exercise," Britney, 26, continued. "I love it." The gym isn't the only place where Britney's getting serious. The former junk-food addict is shaping up in the kitchen, too. "Her eating habits were so bad, and she ate so sporadically, doctors suggested her dad do everything he could to get Britney to eat three times a day," says a family insider. Britney's dad, Jamie, has taken the advice one step further and has put Britney on a healthy diet. Some of Brit's motivation is fueled by wanting to fit into her old clothes, but she's really focused on regaining her physique to revitalize her career- and benefit her little boys. Says the family insider, "Britney wants to be healthier for Sean Preston and Jayden James," who are living with their dad, Kevin Federline, full time. "Almost everything she does brings her one step closer to getting her boys back." Read more about Britney's new body in the latest issue of Life & Style, on newsstands now!
