Pregnant with her fourth child, Brooke Burke tells Entertainment Tonight that she owes her bikini-ready body to her rigorous workouts – and a few other secrets, PEOPLE reports.

"I’ve been doing Pilates for eight years. I actually started with my first pregnancy. I’m a big believer in staying fit during your pregnancy," says Burke, 36, who is engaged to actor David Charvet.

"I know a lot of women are a little afraid to work their abs, or are afraid of core work, but I think it supports your back and I think it helps for an easier delivery and it makes us feel good," says the actress.

Burke, maintains that exercise helped her get back in share faster after delivery. "The more fit you are during your pregnancy, the quicker you're going to bounce back. I probably started up two weeks after delivery and I felt I could handle that."
