Kady explained to Women Fitness that she has developed a workout that can be done anytime, anyplace. "The good thing about my workout routine is that all the exercises you can do literally anywhere, no gym machines are needed," she said. "I love leg day so my go to routine are lunges, walking lunges, squats, squat holds, jumping squats and then ab exercises (crunches, v holds and sit ups)." She also revealed to Daily Star that she trains four or five times a week for 45 minutes per session. "I mainly focus on my lower body, so things that work the glutes, legs, and abs," she said, revealing that she prefers body weight exercises over using machines.

Kady also reveals that a healthy diet is a big part of her fitness plan. "I just try to eat well and I'm lucky that I really love healthy food. I tend to eat lots of protein and vegetables while trying to avoid carbs and sugar," she told Daily Star. "That usually means I end up scoffing lots of chicken, eggs, smoked salmon, steak and cottage cheese. I make my own pizzas that are full of protein, too, and I love pancakes with blueberries and raspberries." 

Kady maintains there is one thing that's got to go if you want to blast belly fat. "Getting rid of your belly fat is pretty much down to changing your diet and quitting sugar in particular," she told Daily Star. "Sugar is basically just useless calories and if you consume too much it's stored as fat directly on your stomach." If you love sugar—and you love sugar, don't even try to deny it—then breaking your desire for it may not be possible. But what is possible is to reduce sugar's impact on your body, and to protect yourself from its consequences while stripping away unwanted pounds.

While she focuses on weight and strength training to build muscle, she turns to cardio to blast calories. "Cardio is good for burning those excess calories, so going for a run or doing a high intensity workout is a good idea," she told Daily Star. Great idea. Plus: If you stop thinking about burning calories when you exercise, and start thinking about burning sugar, you'll begin to see why short, high-energy bursts of exercise make more sense. While long, slow workouts do indeed burn off sugar, the process takes quite a bit of time, and they don't really touch the extra sugar that's stored in your muscles. But when you do shorter, high-intensity workouts, you quickly burn off the stored sugar in your muscles, causing your body to melt down fat in order to replace the missing glycogen. And when you work out before a meal, you double your benefits; you not only cause your body to convert fat into sugar, but you create a big hole for all those delicious new calories to fall into, before they can be converted to fat. 

Because her workouts are so intense, Kady makes sure to hydrate with both water and coconut water. "So how much fluid does the average, healthy adult living in a temperate climate need? The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is:

• About 15.5 cups (3.7 liters) of fluids a day for men
• About 11.5 cups (2.7 liters) of fluids a day for women

These recommendations cover fluids from water, other beverages and food. About 20% of daily fluid intake usually comes from food and the rest from drinks," says the Mayo Clinic.

Another one of Kady's workout? Yoga. The star can be regularly found striking a pose in her social media posts. "Yoga mornings," she captioned a recent clip highlighting her practice. "Every person has a different body with different abilities. You may need to modify yoga postures based on your individual abilities. Your instructor may be able to suggest modified poses. Choosing an instructor who is experienced and who understands your needs is important to safely and effectively practice yoga," says the Mayo Clinic.

Kady does allow herself to indulge on occasion. "If I was on a cheat day I'd happily munch through a big chocolate brownie but I wouldn't do it on the days I was working out – I'd feel like I'd just undone all the hard work I'd put in," she told Daily Star.
