Molly doesn’t go on drastic diets. “It's more about living healthy and how you're feeling," she told Women's Health. "I truly, truly don't like the word 'diet.' I don't even like the scale. I use a pair of jeans; the jeans don't lie I can tell you that."

2. She Is Committed

She is also totally committed to fitness and a healthy way of eating. "This does not come naturally," she told Shape. "I have to work out 60 to 90 minutes at least five days a week and stick to a high- fiber, low-calorie eating plan." "You're not in this alone. Invite friends or co-workers to join you when you exercise or go on walks. Work out with your partner or other loved ones. Play soccer with your kids. Organize a group of neighbors to take fitness classes at a local health club or work out together virtually on video," says the Mayo Clinic.

3. She Does HIIT Workouts

Molly does HIIT style workouts, after years of being a cardio queen. “I used to be that girl who wouldn’t pick up the 2-lb weights at SoulCycle with the fear that I’d bulk. That mentality has shifted drastically,” she explained on her blog.

4. Her Workouts Are Short, But Intense

Molly’s workouts are short but sweet. "On good days, workout. On bad days, workout harder,” she captioned it. “Today’s circuit is what I do when I just have 20 minutes with @lauralizkeller [Sims' personal trainer] to get it in and still break a sweat!” Usually she does 45 second intervals of the following, with the entire set repeated two to three times: jumping jacks, modified pushups, tricep dips, squat jumps, leg raises, burpees, ab lateral bend and hold. To make it harder, she uses ankle and wrist weights the entire time.

5. She Does Intermittent Fasting

6. She Stays Away From Sugar

Molly’s diet is centered around mostly veggies, lean proteins, and fresh fruits. "I tend to stay away from anything super sugary, like orange juice grapefruit juice, because it really spikes me," she told Women’s Health. "I try to stay away from dried fruits; it's ultimately full of sugar.”

7. She Doesn’t Eat Gluten

Molly minimizes her gluten intake. "It's not that I'm celiac; I just feel better when I have less of it," she told Women’s Health. "I don't care if I'm being rude to the rest of the table," she added to Shape, revealing that she always orders a salad first thing after sitting down at a table to keep herself from snacking on carbs. Then I'm not tempted to reach for that bread."

8. She Loads Up on Healthy Fats

Molly fuels up on healthy fats. “I would have never eaten an avocado 10 years ago if you paid me,” she told Health. “Like, are you joking? But now, instead of binging [and] not eating all day, eat it and then you won't binge.”

9. She Motivates Herself with Bags and Jewelry

Molly sets fitness goals, like “I'm going to get up every morning at 6:30 to work out," she told Shape. "Then, when I've kept with it all week, I give myself something I really want, like a new handbag or a piece of jewelry I'm coveting."

10. She Works Out with Her Husband

Molly has a great workout buddy: Her husband. "My mom was on my daddy to exercise all the time," she told Shape. "She was like, ‘Listen buddy, if I'm doing this, you're doing it too.' and I agree!" She maintains that she and hubby Scott Stuber help keep each other accountable.
