1. She Worked With Two Trainers to Feel Like Herself Again

She worked with not one, but two trainers to shed 100lbs. Harley Pasternak and Sydney Liebes helped Simpson with her full body workouts multiple times a week for 45 minutes. After slimming down, Jessica decided not to focus on the scale. She dropped 100lbs in just 6 months, then stopped putting emphasis on the number. “I couldn’t handle being so big and my ankles were swollen. So I’m just happy to feel comfortable again. I was literally uncomfortable for so long that now it’s just nice to relax,” she said.

2. She Followed Her Doctors' Advice

She’s always worked with her doctor on what weight loss plan she should try. She enjoyed Weight Watchers, even acting as a spokesperson for them at one point. During her pregnancy, her and her doctor decided she would not be following the Weight Watchers plan while pregnant. They work closely on what’s best for Jessica’s health.

3. The Challenges Grew, But She Faced Them Head On

Jessica has fluctuated with her weight on and off for years. After each baby, it became that much more difficult. Pasternak helped her each time. “My mantra is you get lean in life, and strong in the gym. So the majority of the weight loss actually came from everything she did outside of the gym, and then everything in the gym is about toning and tightening,” Pasternak says.

4. She Cheats Here and There

Jessica is allowed to cheat here and there. “If she has a birthday party one night and a date night another night, she’s going to indulge both of those nights, but that’s it. It’s about balancing in a way that doesn’t make it painful or too much of a departure from your life before that,” said Pasternak. Jessica admits it’s been a lot of hard work.

5. She Enjoys Walking

One of the first things Simpson did to get to a healthy place after Birdie was born is start walking. It’s low impact and gets the body moving. She’d slowly increase her daily step count, aiming for 12,000-14,000. “If I haven’t moved enough, I’ll make sure and get in extra steps the next day,” she said.
