New moms sometimes try all different types of fitness routines to help them lose baby weight, but actress Julianna Margulies has only stuck with one — Pilates. She admits that "I don’t have a trainer" but gives credit to "good genes" for helping her with the weight loss. The 42-year-old also has one secret to her fitness plan that most don’t think about — her 9-month-old son Kieran Lindsay.
"He’s great. That’s a workout! He’s 22 pounds — a lot of lifting."
Kieran is the first child for Julianna and her husband Keith Lieberthal. The couple were married November 10, 2007.
