Nicole Kidman
During her pregnancy, Nicole Kidman kept in shape with regular spinning sessions, vinyasa yoga classes and power walks. Days after the arrival of daughter Sunday Rose, Kidman made a trip to her local yoga studio, and it wasn't long before she was back in spin class -- which helped her shed most of the baby weight in just two months. "To step back into all of this is a bit of a shock," the actress said when she hit the red carpet at the Women in Hollywood Tribute in a body conscious Prada dress.

Halle Berry
Six weeks after the arrival of daughter Nahla, Halle Berry wowed the crowd at the Jenesse Silver Rose gala when she arrived wearing a very sexy leopard-print Dolce & Gabbana dress. Trainer Ramona Braganza says Berry stuck to a modified pre-natal exercise plan right up to the seventh month of her pregnancy, which made it easier to bounce back after giving birth. "You can't do a lot in the second trimester, but we kept it going with light weights and a lot of breathing and yoga," said Braganza.

Salma Hayek
To drop the 30 pounds she gained while pregnant with daughter Valentina, Salma Hayek combined the popular Diet Designs plan -- ready-to-eat meals with a precise balance of lean proteins, unrefined carbs and healthy fats -- with a consistent exercise plan. "It takes you nine months to get it, and nine months to lose it. There are shortcuts, but it's not good for the baby," Hayek told Oprah Winfrey of her approach to regaining her figure without crash dieting. "I've lost most of the weight and I'm very proud of it because it's been really hard work."
