The segment was discussing whether pole dancing as a form of exercise is too sexual for young children.
The children's pole dancing teacher, Zoe Hardy, 33, and two of their mums, Lisa Grosse and Lorraine Handbury, went on the show to defend the hobby.
Using the suggested #PoleDanceDebate, viewers expressed their thoughts on Twitter, both positive and negative.
"There are so many other ways to get kids into fitness without teaching them pole 'fitness'," tweeted one person. "Especially with those outfits."
Others also commented on the girls' outfits, which were short black hot pants and white cropped shirts tied up above their belly.
#PoleDanceDebate the shorts those girls are wearing are NOT ones worn by school girls in the gym. Unbelievable.— Róisín (@roisinramone) February 16, 2016
No way in hell would I have my daughter at a pole dancing class! 🙈 #poledancedebate— Lauren (@laurenlillyx) February 16, 2016
However, there were some people who disagreed that this type of exercise was "sexualising" children, with some praising its benefits.
there's nothing wrong with it, it's us who are sexualising children #poledancedebate— court (@fluoxetinefairy) February 16, 2016
the #PoleDanceDebate is ridiculous. pole fitness is an excellent way to exercise and people who sexualise it are perverts! 🙃— ella (@_maccers_) February 16, 2016
I don't see the problem with young children pole dancing? It's fantastic for upper body strength and fitness #poledancedebate— Maddie (@MaddieHarrop) February 16, 2016
#poledancedebate Pole fitness is an excercise. The people who have a problem with it are the ones sexualising young girls who are having fun— cat (@ccatelizabeth) February 16, 2016
#poledancedebate why should young girls be brought up thinking they shouldn't do something because they're going to be objectified by men?— Leah (@ljevans525) February 16, 2016
The debate was sparked by a recent comment by psychologist Emma Kenny who publicly said she disagreed with children pole dancing for fitness.
"For people to tell me that pole dancing isn't sexualised beggars belief," she tweeted.
"Kids shouldn't be gyrating on poles. Adults can do what they like."

Watching the routine on This Morning, Kenny said: "It's got connotations to something far more salubrious.
"And even the outfits seen in the studio today I don't think are resonant of childhood."
One of the mothers, Lisa Grosse, explained that her daughter Tilly-Mae, eight, was overweight until she started pole fitness lessons.
She added: "It's fitness. There's nothing provocative about it."
And 11-year-old Tilly's mum said: "She likes to challenge herself, so why not?
"There’s a pole in the playground they play at, they climb up it, they spin round it and down. What’s the difference?"
