Kristen Bell, 33

With the help of Bar Method classes, the 5’1″ House of Lies star has shed 28 lbs. since her daughter Lincoln was born in March. But while she admits she’s still carrying an extra 15 lbs., Bell is in no rush to lose what she calls her “Lincoln Leftovers.” “I’m going to continue working out and see where it goes,” Bell told Redbook. “If this is where my body wants to be, so be it. I’m not going to make myself miserable.”

Jenna Dewan-Tatum, 32

Six weeks after welcoming Everly in May, the 5’3″ actress returned to the set of Witches of East End “and looked flawless!” says a source. An avid runner, Dewan-Tatum also credits her petite post-baby size to her vegan diet. “I took care of myself, and I eat really healthy,” said Dewan-Tatum, adding, “I worked out the whole pregnancy up until the day I was giving birth. That helps everything stay intact.”

Shakira, 36

The 4’11” Voice judge says losing post-partum pounds was “stressful” after the January arrival of her son Milan. But trainer Anna Kaiser mixed dance-based cardio with strength training to help tone Shakira‘s famous abs (and hips!) four times a week. “Shakira is very focused,” Kaiser said.

Jennifer Nettles, 38

To trim her waistline, the 5’8½” Sugarland singer teamed up with a trainer three months after delivering her son Magnus in December. But she didn’t rely on thrice-weekly resistance-training sessions alone. “Diet is 75 percent of weight loss,” Nettles says. So “I cut back on sugar and carbs.”

Malin Akerman, 35

In addition to signing up for Paleta, an organic-meal-delivery service, Akerman has been alternating between hiking, cycling and Pilates to get her pre-baby body back following the birth of her son Sebastian in April. Her motto? “Always keep your muscles guessing,” the 5’9″ star said.
