Losing It Fast

They're breaking speed records, but celeb moms like Denise Richards know that getting back in shape after baby – whether it's the first or fourth – takes sweat and sacrifice


She put on 30 lbs. while carrying Lola (born June 1), but Richards, 34 (from left, on May 30, June 17 and now), had a secret weight-loss weapon: “It’s called the Stress Diet,” she says, half-joking, – and alluding to having filed for divorce (from Charlie Sheen) in her sixth month of pregnancy. But mostly she can thank her work with trainer Garrett Warren: She's been kickboxing and doing abdominal exercises four to six times weekly – and adhering to a portion-controlled diet.
