So how does Duchess Kate get her legs looking so toned?
The royal has been known to incorporate a hybrid of cardio and weight training into her lifestyle. From running to weight lifting, cycling to rowing, yoga to HIIT, the sporty Duchess' workout routine certainly isn't for the faint-hearted.
Duchess Kate is known to love running, with Mike Tindall, who is married to Prince William's cousin Zara, describing Duchess Kate as an "engine", claiming his dream rugby team would involve the 40-year-old royal on one wing "because she loves running, she can run all day!"

"Regardless of your body shape and size, runners tend to have powerful legs as they are constantly working the large muscles of their body," says David Wiener, who works with fitness app Freeletics.

2. Weight Training
Anyone into fitness knows that weight training is the key to progress - and the Duchess certainly doesn't skip leg day in the gym!
It's well documented that the Duchess loves tennis, even taking to the court with Emma Radacanu last year, and while the sport might seem like an arm workout, it exercises the legs too.
Duchess Kate enjoys tennis
"Many people think that tennis simply relies on your arms and wrists. In reality, the movements and actions in tennis require your whole body. Even actions that seem simple at first, like hitting a ball, require your whole body to be in sync," says Tim Benjamin of audio fitness app WithU, which offers tennis-inspired workouts.

Tim compares tennis to HIIT, due to the short, sharp, movements that are used to move around the tennis court. "They are a great way to improve cardio and lung capacity."
Duchess Kate and Prince William have been pictured enjoying the great outdoors, and hiking with their dogs, on many occasions, and while hiking might not get the heart rate up quite like other activities that Duchess Kate loves, it's key for leg toning.
"One of the most important (yet underrated) exercises to get toned legs is walking," confirms David. "Walking has so many different mental and physical health benefits and is incredibly important if you want toned legs.
Hiking is a great leg work out
"I always recommend that if you can walk somewhere, then walk! Swapping that 10-minute car journey for a 20-minute walk can truly be the difference in not only leading a healthier lifestyle, but helping get amazing toned legs."
The mum-of-three has been spotted cycling on numerous occasions – an exercise key for toned legs.

"Cycling is another great exercise which helps you tone your legs as you will be working your quadriceps when you pedal, which helps strengthen and tone your legs," explains David. "You will also be working the hamstrings and calf muscles, which gives you a true full leg workout."
