Mike Tindall shares rare update about Princess Kate in new interview

Aside from dabbling in sailing, cycling and yoga, it is believed the mother-of-three follows an exercise routine with cardio and weight training.

Mike Tindall, 45, who is married to Zara Tindall, Prince William's first cousin, made a revelation about Kate in a new interview.

Sharing a glimpse inside the Wales family's passion for sports, the former rugby union player said: "George loves his football.

"I've played numerous times in the garden with him. He's passionate about Aston Villa, too.

"Wherever he is, he'll sit down and watch that game."

He continued to tell The Telegraph: "They're just a family who love sport. Catherine loves her running."

Elsewhere in the interview, Mike spoke candidly about his own family life with his wife Zara, 43, and their three children, Mia, 10, Lena, six, and Lucas, three.

Hailing from a sporty family, equestrian Zara won silver in the 2012 Olympics and Mike was part of England's 2003 World Cup-winning team.

Therefore, it is perhaps no surprise that the Tindall children are following in their parents' footsteps.

Reflecting on Lucas, Mike shared: "You can't stop him. He wants physical contact. He wants to be wrestled.

"He imagines himself as a ninja, and he just walks around with sticks whacking people."

Mike added: "He's such a typical boy, you almost have to run him into the ground with exercise, like a dog, otherwise he won't sleep.

"You're built that way. So, being fully masculine, which a lot of rugby players are, is not a bad thing."
