Jessica Alba may have lost her baby weight in record time, but it wasn't because the 30-year-old mother-of-two became a slave to the gym.
"I didn't gain as much weight with my second pregnancy, so I think that really made a big difference," Alba told Us Weekly while hosting Swarovski Elements' holiday lights installation in Beverly Hills Monday.
"I did prenatal yoga up until the very end," she added. "I just made healthier choices. I started working out and not going too crazy, but I did what was safe and what the doctor approved."
A source recently told Us that Alba "was on a mission to get her body back" after welcoming her second daughter, Haven Garner, in August. "She missed being a sex symbol."
Two weeks after giving birth, Alba did 40 minutes of cardio on a stationary bike and the elliptical. Now she tackles 90-minute sessions four days a week with get-fit guru Yumi Lee at L.A.'s Fitness Factory.
Since Haven Garner's August arrival, the Little Fockers actress said she's become more confident as a mother.
"It's nice to enjoy having a newborn instead of being overwhelmed and wonder if everything is going to be okay," Alba told Us. "Now I'm like, 'Oh, she'll be fine!' They're so sweet together."
Alba married documentary producer Cash Warren in 2008, the same year they welcomed their first daughter, Honor Marie.
