Cristiano Ronaldo’s son is worryingly ripped for a seven-year-old

Cristiano Ronaldo has sparked concern among his fans after posting a photo of his seven-year-old son without a top on

Cristiano Ronaldo's Instagram page is a healthy balance of football snaps and adorable family moments with his girlfriend, Georgina Rodriguez, and his four children.

But the health of his eldest, seven-year-old Cristiano Junior, has been called into question by some of his 121m Instagram followers after he posted a snap of the little lad pulling a weightlifter's pose.

Cristiano, 33, who welcomed twins Mateo and Eva last summer via a surrogate and baby Alana with girlfriend Georgina Rodriguez last November, posted the photo on the social media site yesterday.

He captioned the photo: "Jr say daddy I'm gonna be like you!!! What do you think??"

Many of Cristiano's fans gushed over the little boy, saying that he was cute and the spit of his famous father, but others were worried for Cristiano Junior.

Despite the fact that it has amassed 5.2m likes since it was posted, many fans rushed to the comments section to express their concern for the little boy.

One simply wrote: "Steroids," while others wrote: "Anorexic," "I think he should take some food!" and: "Horrible😱 he is a children, not a little man."

One commented: "That's not for little kids," while another added: "Omg is he 7?!" and: "Gosh, spare him. He's a child!"

Another wrote in Cristiano's native Portuguese: "You have malnourished!"

Len Almond of the British Heart Foundation's National Centre for Physical Education has spoken out in the past about young children overdoing it when comes to exercise.

He told the Daily Mail: "Young children should absolutely not be doing weight training or resistance work.

"There is always a danger of children over-doing things. Lots of budding footballers who train hard from an early age suffer later with their legs. Too much exercise can make children ill and their immune systems suffer."

Professor Russell Viner, Officer for Health Promotion at the Royal College of Paediatrics and Child Health, provided some general information on child health, telling us: "For many younger children and teenagers of an appropriate weight, you can often see some of their ribs and musculature. Seeing some of the abdominal muscles can be quite normal and is not necessarily a sign of being ’toned'.

" However, 'six-packs' and the like are not something we would encourage children to be focusing on achieving as it can breed excess concern with body image.

"Adults actively exercise their core muscles in order to gain strength, stability and features such as ‘six-packs' as they generally don’t get enough core muscle exercise through modern daily-life activity – whereas generally children should get enough exercise for all muscle groups from healthy play."
