Princess Diana's Personal Trainer Opens up about Their Workouts with William & Harry in the Palace

Princess Diana's personal trainer, Jenni Rivett, shares details around the Princess's workouts and physical activities with Prince William and Prince Harry. She also divulges the eating disorder Diana struggled with.

Aerobics, rollerblading, and step classes. According to her personal trainer, Jenni Rivett, these are some of the activities that helped Princess Diana maintain her svelte physique. Rivett took on the Princess as a client in the 90's.

Rivett says she was recommended to Diana in 1991, and it wasn't long before she discovered the Princess of Wales loved exploring the latest workout crazes of the time.

According to Rivett, step classes were a favored go-to and cardio sessions and going for power walks in the Kensington Palace Gardens. Rivett even took it upon herself to teach Diana how to rollerblade.

Rivett says what made the workouts more memorable for Diana was when her sons, Princes William and Harry, would participate. Rivett revealed how the boys enjoyed being a nuisance to their mom, adding:

"She had a very special bond with William and Harry and would love to embarrass them, too — her sense of humor was one of her greatest traits."

The personal trainer recounted the friendship she developed with the Princess, saying Diana liked the fact that she didn't socialize in the Royal Circle and wasn't familiar with all the royal rigmarole.

On one occasion, Rivett said she was stunned to discover she was meant to curtsey every time she greeted Diana. After apologizing to the Princess for not being aware, Rivett said the Princess laughed it off.

The mom of two was also fiercely protective of her sons.

When Diana endured a public separation and divorce from Prince Charles, Rivett was by Diana's side. She added Diana opened up to her about her struggles with bulimia.

The Princess would later go public with her eating disorder, which Rivett found admirable as it helped put so many other people battling eating disorders at ease. The personal trainer also sought to assist Diana, saying:

"I just encouraged her with healthy eating and I honestly believe the exercise helped her manage her bulimia."

Diana enjoyed sharing her workouts with her sons, given all the times she was a doting mother who abandoned royal protocol. This includes a beach holiday to Necker Island in 1990, where her sons buried Diana in the sand.

The mom of two was also fiercely protective of her sons, as experienced by a camera crew following the family on a ski trip in 1991. Diana walked up to them to ask them to stop pestering them and allow the family to enjoy their vacation.

Intrigue has always followed Diana and her sons, and more was revealed about the trio's tight bond in letters Diana had written to Cyril Dickman, who was previously stationed as a steward at Buckingham Palace.

In one letter penned in 1984, the mom gushed about how fond William was of his baby brother, smothering him in hugs and kisses. Diana had written Dickman back after he had sent a congratulatory card to the mom following Harry's birth.
