Amanda is a vegetarian. “For me, it’s lots of avocado, chickpeas, and quinoa salads. I’ve been a vegetarian since I was 15, but I do eat fish. The children are vegetarian, too, and Chris eats meat, so I often make three different meals,” she told The Daily Mail.

2. She Does Yoga

Amanda maintains that yoga benefits her both mentally and physically. “I practise a form of yoga, which is more to do with breath control and strength than getting sweaty,” she explains. "Kundalini yoga is all about breath work, so I took it on to build my strength. A lot of people advised me to do it for calmness, too,” she added to The Sun.

3. She Hydrates

Amanda keeps her body fueled with liquids. “‘I drink loads of water — a lot of coconut water,” she told The Daily Mail. "About 50-75% of your weight is water! Getting enough fluid in your diet is important for everything in your body to work well and be healthy, including your heart, digestion, brain, muscles and skin. Fluids deliver nutrients to your cells, maintain a balance of nutrients, and remove wastes from your body. Good hydration supports normal energy levels, decreases risk of kidney stones, prevents constipation, and is associated with a reduction in urinary tract infections, high blood pressure, fatal heart disease and stroke," says the Cleveland Clinic.

4. She Lives by Moderation

Everything in moderation is the mantra Amanda lives by. “You have to enjoy life. I eat everything. Drink everything. I had a friend once who didn’t make it to her 50s and her biggest regret was she spent her life on a diet. I don’t diet,” she told The Daily Mail.

5. These Are Her Sweat Methods

Amanda told the Daily Mail that running, hiking and boxing are her go-to forms of exercise. However, she also goes on fitness retreats. “I go to a fitness camp in Portugal before the live shows,” she told them. One place you won’t find her? "I like to keep active. But I can't stand gyms. I like to run for an hour a week, as I feel great afterwards. It's also time to myself, which is worth its weight in gold,” she told The Sun.
