2. Do HIIT Workouts

Molly claims that using weights and doing HIIT workouts was a major game-changer for her body. “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 revealed on her blog. In a video for Women’s Health she revealed that she works out first thing in the morning at 6:30 am, after meditating for a few minutes outside with a cup of coffee.

3. Do Load Up on Healthy Fats

“I would have never eaten an avocado 10 years ago if you paid me,” she revealed to Health about her favorite healthy fat. “Like, are you joking? But now, instead of binging [and] not eating all day, eat it and then you won't binge.”

4. Do This 20-Minute Workout

"On good days, workout. On bad days, workout harder,” she captioned an Instagram video, which highlighted her go-to short but intense workout. “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!” Her quickie involves 45 seconds intervals of the following, with the entire set repeated two to three times: jumping jacks, modified pushups, tricep dips, squat jumps, leg raises, burpees, abd lateral bend and hold – all while using ankle and wrist weights the entire time.

5. Do Intermittent Fasting
