The mother of two quickly shed the baby weight that she put on while pregnant with her son Ace Knute Johnson and in a new interview with USA Today, the fashion designer revealed that she's already back to her pre-pregnancy weight.
So, how did she do it?
Well, we know Jess watches what she eats, because she's a spokesperson for Weight Watchers, which she said she "jumped back on" as soon as Ace was born.
Also, she's moving around a lot. "With both kids, I'm running up and down my stairs a million times," she revealed. "Kids can keep your metabolism going. Eric (Johnson) and I go on walks together. I try and walk about 4 miles a day consistently. It makes me feel better."
As if that wasn't enough, Jessica is also working out with a personal trainer four days a week. "It's a lot of resistance training, lots of lunges and squats," she said. "There are bursts of cardio throughout the workout as well."
Sounds like she's working hard...and it's definitely paying off!
