Adriana Lima is back in supermodel shape just six months after giving birth to her daughter Valentina -- and it was no trouble at all, she says.

"It wasn't that bad," Lima told at Thursday's 3rd Annual Aerospace High Performance Championships in NYC. "It was easy."

Last November, the Victoria's Secret catwalker and husband, NBA star Marko Jaric, welcomed little Valentina, their first child; they had eloped over Valentine's Day 2009.

Lima, 28, works out with trainer Michael Oladjide at the the Aerospace High Performance Center. How many times a week? "Everyday," she said. "Often I come twice in one day! It can be anywhere from one hour to...two hours," doing boxing, jump rope and other high-impact cardio routines.

As for her diet, the Brazilian bombshell stuck to a no-carb, all-protein regime for three weeks. She's back on carbs, but "now I just try to watch what I eat and eat good, nutritious food." But no counting calories, she said.

Lima loves new motherhood, she added. "Every day I discover something about her," she gushed. "Every single day is a pleasure to see her. I'm always rushing home! I never rushed to go back in my life! It's the best."
