Dua opts for hardcore, short HIIT workouts instead of long, easier ones. "It's high-intensity interval training, but it's so quick, it's over before it's even started," she told Vogue about her sessions. Each runs 15 minutes and consists of jumping jacks, mountain climbers, and burpees. Why should you consider HIIT? The Mayo Clinic confirms "you'll burn more calories," with them. "The more vigorously you exercise, the more calories you'll burn — even if you increase intensity for just a few minutes at a time," they say. 

Bella opts for longer workout sessions, telling E! News that her workouts are a whopping two hours long."I train and I work out hard for two hours — I don't like to do the whole yoga thing. I think yoga is calming, it's amazing, but if I'm going to go for it, I'm going to go hard," she said. "Put in 100% from the start to the end of a workout. There is nothing better than to push yourself to the limit, while making the most of it. Going to the gym for two hours with only 50% motivation is the best way of erasing the feeling of accomplishment and well-being that boosts self-confidence that you get from a workout," she added to Vogue France.

If you want flat abs a la Dua, put in the work. The singer told Urban List that she focuses on her midsection. "I think different variations of crunches like bicycle crunches are good. Leg raises are also great unless my back hurts. Planks are good although almost certainly my least favourite!" she said. 

Bella has "really low blood sugar" so she has to "eat all the time," she revealed to Harper's Bazaar to keep her energy up. "I like having a good protein meal because I get really tired if I eat too much, so I try to fill myself up with things that will make me feel good," she explained. She also makes sure to have something in her tummy prior to a workout. "I count on a smoothie, a juice or a protein drink 30 minutes before the session," she added to Vogue Paris. "After the session I eat something full of protein like chicken and wholegrain rice. It's ideal to strengthen the muscle mass and to increase the effects of the session."

In addition to HIIT workout, Dua does yoga, Pilates, and boxing. "Whatever it is, I try to change it up every day to keep things interesting," she told Urban List. "I like that it's definitely a full body workout. Since starting boxing, I've probably been in the best shape ever. It's also a great stress reliever." 

Bella revealed to Harper's Bazaar that she stays energized with a few different beverages. "I order a lot of green juices and keep them around on set. I have ginger shots in a cooler, and I'll drink one if I'm feeling low," she revealed. "I'm also a big coffee drinker. I'll have three espressos before noon."

In addition to having a bikini buddy, Dua relies on pals to stay motivated with fittness. "I would always be that person who made a new year's resolution, get a gym membership and then show up twice in the first week of January and then never go again," she told Urban List. "Now I love workout classes or working with a trainer. I feel like I'm pretty useless on my own, so I prefer being around other people working out with me."

Unlike the supermodel stereotype, Bella doesn't starve herself to stay thin. In fact, she tries to eat a hearty breakfast daily. "If I have the morning off, I'll either make eggs and sausage, and eat breakfast at home, or go to the bagel store below my apartment. … My go-to is an egg sandwich on a plain bagel," she told Harper's.
