Her busy diary means she has to juggle her royal duties as Princess of Wales with being a hands-on mum to her three children.
So it wouldn't be surprising if that left her with little to no time to fit in any all-important workouts.
But with sporty Kate being a fan of keeping fit, she once revealed her unusual yet fun way of exercising - and how she squeezes it into her schedule.
Kate divulged her fitness regime earlier this year while hosting a reception for England's Wheelchair Rugby League team, which won the World Cup last year.
Asked whether her children were interested in rugby, she said: "We're always slightly competitive with each other. They all love sport and Louis is mad about rugby. They are at an age where they just love running around."
The princess then divulged her own fitness schedule and added: "I do it all: whenever I can squeeze in exercise I do, even jumping on the trampoline with the children before school."
Kate then beamed as the players invited her and her family to join them in training.
Later today, Kate will have another chance for a workout when she takes part in rugby drills to raise awareness around the lifelong impact of early childhood and the importance of community settings in early years.
Kate, patron of the Rugby Football Union, will meet local and national men’s rugby players at Maidenhead Rugby Club to discuss the Shaping Us campaign, hear more about their childhood experiences, and speak about the role of community settings in supporting children and parents.
The princess will participate in rugby drills before heading into the clubhouse where she will hear about childhood experiences, fatherhood and the impact that settings such as sports clubs can have on creating a network of support when raising children.
The Shaping Us campaign was launched by the princess and the Royal Foundation Centre for Early Childhood in January 2023 and aims to highlight the importance of supporting young children and those caring for them.
Others attending the event will include Shaping Us champion, former England rugby player and father-of-two Ugo Monye, representatives from Maidenhead RFC and Si Trower, the founder of mental health charity Brave Mind.
The princess has been a long-term advocate for raising awareness around the importance of early childhood before starting the campaign earlier this year.
Last month Kate was joined by rapper Professor Green, a supporter of the princess’s early years Shaping Us campaign when she sat down with a group of young people who have been through the care system.
