Exercise regimen: I train in the gym about six days a week for 11/2 hours each time. I do CrossFit - a combination of Olympic lifting, gymnastics, and powerlifting - which trains strength, endurance and agility. I also do a bit of yoga for 30-45 minutes daily to improve my flexibility and mobility, as well as to de-stress and wind down.

Diet: I've been a vegan for five years. My goal is to break down misconceptions that we need animal products to be lean, healthy and strong. I always drink a big glass of water with a pinch of lemon juice when I wake up. Breakfast is usually a smoothie that consists of bananas, spinach, chia seeds, coconut water, Himalayan sea salt and hemp seeds. I believe in eating good and clean plant-based food like rice, vegetables, chickpeas, kidney beans, tofu.

Exercise regimen: I alternate between 25 laps at the pool and spending 40 minutes at the gym every day. I do push-ups and planks to work on my arms and abs, as well as squats, leg raises, and elliptical workouts to focus on my core and legs. I used to dance competitively in a hip hop group, but now I dance for leisure once every fortnight.

Diet: I drink at least two litres of water a day, and I love salads and greens like spinach and kale. My breakfast is usually a super food smoothie that may include cacao and mesquite powder, spirulina, chia seeds, bananas, almond milk and berries. I'm a big believer in organic food. I don't eat a lot of carbs. I take small meals and snack on grains. My weakness is ice cream and chips, but I try to eat vegetable chips when I want to indulge.
