Kendra Wilkinson has said it was a "culture shock" to see her post-baby body. But now?
"I don't want to go back to the size-2 jeans. I want to stick to my curves," Wilkinson, 24, says while shooting her Us Weekly fitness DVD, Be a Knockout With Kendra (www.kendraworkoutdvd.com), with celeb trainer Nicky Hollander. "I'm focusing on sculpting my body... I'm a huge athlete."
Wilkinson, who added 50 pounds of baby weight to her 5-foot-4 frame while pregnant with Hank Baskett IV, will release her vid -- which also features a bonus booty workout -- later this summer. (See how another celeb got fit.)

"[Taping the] fitness DVD... gave me the motivation and drive to lose the weight," she says. Plus, Hollander's wife "had three C-sections, so he knows what's going on with my body," explains Wilkinson, who gave birth via C-section last December after spending more than 24 hours in labor.

After watching back some of the footage, which shows the E! reality star doing football drills, pushups and even balancing now 5-month-old Hank on her stomach, Wilkinson enthuses, "God, I love my legs and my ass!"
