Chris Barker, Zara's trainer, revealed to Glamour UK that his star client is devoted to fitness. The two train together three times a week. "A usual week would be Monday, Wednesday and Friday training with me with two additional cardio sessions if she can. I like to program full body days, so we are working out as much of the body as possible, however I will make sure that we are able to focus at the same time on certain areas like her bum, for example, which she has wanted to focus on."

Zara does a lot of deadlifting and squats. "Learning how to perform these exercises correctly are a key foundation in any exercise program," Barker told Glamour. He added that learning how to activate the glutes property is crucial. "It is then using the key exercises like deadlifts, squats and hip thrusts and focusing on progressive overload (the principle behind most resistance training programs where you are either trying to lift a greater load or the lift the same load a greater number of times, thus putting the muscles under enough stress to elicit a response – meaning the muscle grows and becomes stronger)," he said. 

Zara uses fitness apps to track her calorie intake and portion sizes. However, her trainer maintains that after a few weeks of tracking, she had a better understanding of nutrition. "Like most of my clients, Zara follows a high protein diet; we then reduce her carbohydrates and fats depending on how she is looking and feeling. Zara is a great cook so she has always been very good with this side of things and this is why she looks as amazing as she does."

Zara is allowed to cheat on occasion, per her trainer, who says telling clients they can't drink alcohol or ever eat their favorite foods, "is setting them up for failure," he said. "By teaching the importance of nutrition and how you can still achieve your results while having the occasional drink or enjoying a pizza then my clients tend to adhere to the program better and actually achieve longer lasting results. Zara still enjoys foods that many people would consider 'bad' but if you are sticking to a caloric plan and not going over your calorie levels consistently, you are still able to achieve great results ….and Zara is testament to that."

In a recent Instagram post, Zara revealed she is trying to eat more produce. "For the longest time I have looked at integrating more plant-based food into my diet and just be a bit more flexible with what I fuel my body with, whilst maintaining protein and nutrition intake," she wrote.  "As I mentioned before, ensuring I get enough protein is a priority to me, and not something I have had to compromise when adding meatless meals into my diet!"

Zara is one of the many stars who likes sipping on green juice and smoothies. "Juicy sundays," she captioned this snap of herself. She also likes an iced coffee in the morning.
