She has the perfect smile and toned body -- and many wonder how the Duchess gets in such terrific physical shape.
Like in real life, it doesn't just come naturally -- and takes a lot of hard work and dedication!
And some of Kate's secrets are revealed in the new issue of British magazine Now.
The article reveals she doesn't have a personal trainer, but has developed her own workout routine.
"We can reveal the Duchess owes her tiny, toned figure to a no-frills £13 workout consisting of a gym ball and a pair of dumbbells," according to Now.
"Kate does an hour's workout every morning using the gym ball and dumbbells, which includes some core exercises like squats, sit-ups and arm curls."
Not to mention, she also has a healthy diet, loves sports and gets to go on long walks to tire her dog Lupo out!
