Model Gabrielle Epstein in Two-Piece Workout Gear Shares "Stuff"

Gabrielle Epstein is showing off her gym-honed body. In a new social media post the model wears a crop top and leggings, flaunting her washboard abs. She captioned the series of Instagram snaps, “stuff.” How does the model approach diet and exercise? Here is everything you need to know about her lifestyle habits.

1. 80/20 Diet

Gabby eats healthy most of the time. “I try and follow the 80/20 rule, which is my approach to maintaining a healthy lifestyle rather than a diet philosophy. It’s pretty simple, I try and eat well 80% of the time, and then 20% of the time I let myself enjoy a bit of indulgence. It isn’t about counting calories, denying myself certain foods or cutting out entire food groups, and allows me to enjoy life without feeling guilty about breaking my ‘diet,’” she told Galore.

2. Hydration

Gabby drinks a lot of water. “Staying hydrated is my number 1 tip!” she told Galore. “Water also helps to flush out all the toxins in your system, especially with a bit of freshly squeezed lemon it. Coconut water and green tea are great for detoxing as well.” According to the Mayo Clinic, hydration is important for a variety of reasons. Water helps get rid of waste through urination, perspiration, and bowel movements, keeps your temperature normal, lubricates and cushions joints, and helps protect sensitive tissues.

3. Snacks

“Preparation is key!” Gabby says about snacking. She packs them so she won’t be tempted by high fat foods such as pizza and hot chips when she is out and about. “If I’m spending the whole day at the beach with friends we always make sure we pack an esky full of coconut water, fresh fruit, nuts and organic popcorn,” she added to Galore.

4. Multivitamins

Gabrielle supplements to ensure she is getting the nutrients she needs. “I also take a good-quality multivitamin daily. It’s a great way to replenish your body of essential vitamins and minerals and to protect your general health,” she told Galore.

5. Different Workouts

“I usually mix up my training with running, reformer Pilates, boxing, and yoga,” Gabrielle told Galore. “When I’m away I have 20-30 minute circuit programs that I can do in my hotel room or at a park if I don’t have time to get to a gym – a short workout is always better than no workout at all.”

6. Daily Exercise

“I try and set aside at least 45 minutes to an hour a day for some form of physical activity,” Gabrielle told Galore. “I also try and work physical activities into the itinerary – paddle boarding, surfing, hiking, and swimming are fun activities that will definitely help you keep fit! I also try and eat as healthy as I can on vacation and avoid consuming sugar, processed foods, alcohol and simple carbohydrates. No matter where you are there should be some kind of fresh high-protein, high-fiber food available.”

7. Eating All the Food Groups

Gabby maintains that “cutting out whole food groups to lose weight” is a no-no in her book. “Healthy eating is all about balance, and your body needs a mix of proteins, healthy fats, fruits, vegetables and complex carbohydrates to function and work to its full potential. I think any diet that cuts out a whole food group is dangerous and can’t be sustainable long-term. Eating healthy, nutritious food and exercising regularly is the best diet for a healthy lifestyle,” she told Galore.

8. Morning Workouts

“I usually hit the gym by 5:30am/6am, and workout for an hour-1.5 hours, then I’ll go home and eat breakfast and make a list of everything I need to do that day. Then usually work from home, or from my laptop at a coffee shop, and catch up with my family or my friends,” Gabby told Women Fitness. “I have always been a morning person, but I find I’m much more productive when I get up early and get everything I need to do out of the way as soon as possible to avoid procrastination and I’m a huge list person.”
