I fear for my children in the age of social media, says Logan

I’m not upset and ... how it will motivate me to try and keep doing what I do to the best of my ability.”

Logan said it is essential that youngsters exercise, and that parents must set the sporting standard, so children will not write off their advice as “preaching”.

“I would really like to do something more concrete about the problem we have with fitness in kids, how we persuade them to put their consoles and their computers down and keep active,” she said. “It’s going to be a huge health crisis in a couple of generations if they don’t.”

Her 11-year-old twins Reuben and Lois, are “very sporty”, after being brought up on walks and bike rides.

“For me, the really important thing is seeing your parents being active,” she said.

“It is hard if you’re not naturally into an active life, but that’s what’s going to motivate your kids because they think, ‘Well you do it’.

“It’s like if you sat there and fed them a plate of vegetables, and then you had chips. They’ll think, ‘Hang on a minute, why are you preaching?’”

The broadcaster, who is married to former rugby player Kenny Logan, also spoke of allowing children “not to get too elated with a victory or too disappointed with a defeat”.

“I see this in my son’s rugby at the weekends,” she said. “Some of the teams they play against, the parents and the coaches react like they’re about to win the World Cup: overly aggressive.”

Logan often speaks about being a woman in the maledominated world of sport, and said “it’s something that shouldn’t be dictated by whether you’ve got a penis.”

She won The NEP UK Presenter Award, recognising outstanding achievement by an onscreen presenter in TV, film or digital media in the last two years.
