How do celebrities look so fit just weeks after having a baby?

Halle Berry, Jessica Alba and Ashlee Simpson’s go-to girl Ramona Braganza, Andrea Orbeck, who has trained Heidi Klum and Kim Kardashian, and Ashley Borden, whose clients include Reese Witherspoon and Annabeth Gish, offer up some effective tips to FitPregnancy.com on how the stars get their bodies back after having a baby – and Breaking Celebrity News has the details.

“Many new moms don’t want to do any jumping because their breasts are larger and heavier after having a baby, so it’s uncomfortable,” Braganza, who created 3-2-1 Baby Bulge Be Gone DVD, says, suggesting that women wear two exercise bras for extra support.

In addition to making sure you’re comfortable, “Trust that your workout is going to change your body for the better,” she advises. “Your mental state is important.”
