From the palace to the polo field, Princess Kate and son Prince George are breaking tradition and changing the Royal rules. Subscribe now for an inside look at their adorable adventures only in PEOPLE!
In this week’s cover story, PEOPLE exclusively reveals the secret to her fit form: a top London trainer who worked with the royal mom, 33, throughout her pregnancy.
The trainer, who is popular with an elite clientele of A-listers, royals and executives, “was brought on board while she was pregnant and is super-discreet,” a source tells PEOPLE.
“It’s a lot of money, but you get a lot for the price.”
Included in the package is a tailored fitness routine and regular monitoring.
“The trainer checks in remotely with Kate by phone every day as well as seeing her in person once a week,” says the source.
As for diet, Kate – who breastfed Prince George and is likely doing the same with Charlotte – is a clean eater who has always gone heavy on organic fruits, veggies and lean meats.
The trainer embraces a similar philosophy – with a high-end twist.
“The food is very elegant and actually feels like food you would eat at a restaurant,” says the source.
