Kaur relied on cardio and Pilates to get back on track after giving birth to her son Jaydon. "I used to do cardio for two hours a day," she says. "Whenever I got the time, I did Pilates to strengthen my back which got weakened due post delivering my son."

Kaur enjoys a protein-rich diet for the most part. "Protein is needed for growth and repair of body tissues and is especially important for healthy muscles and bones, particularly for children," says the British Nutrition Foundation. "Good food sources of protein are meat, fish, dairy products, eggs, nuts and soya, beans, peas and lentils."

Kaur is proud of her strong core, especially her abs. "Core exercises train the muscles in your core to work in harmony," says the Mayo Clinic. "This leads to better balance and steadiness, also called stability." "Plank exercises generally strengthen your ability to brace your abdominals,"says exercise physiologist Katie Lawton, MEd, to the Cleveland Clinic. "Planks can also activate other related muscles, such as your glutes (muscles in your buttocks), hamstrings (muscles in the backs of your thighs) and lower back."

Kaur finds intermittent fasting an easy way to manage a healthy diet. IF offers benefits far beyond just weight loss, experts say. "Many things happen during intermittent fasting that can protect organs against chronic diseases like type 2 diabetes, heart disease, age-related neurodegenerative disorders, even inflammatory bowel disease and many cancers," says Johns Hopkins neuroscientist Mark Mattson.
