Ben, 50, could be seen hitting the gym with his teenage son Sam, 19, as they did pull ups.

The footage showed the dad and son doing the gruelling exercise regime as they attempted to hit their goal of 50.

It’s all part of Ben’s determination to stay fit and healthy into older life after hitting his milestone birthday.

But for fans at home, they couldn’t believe how grown up and big Sam has got, as he towered over his dad in the clip.

One said: “He’s so much bigger than you now Ben. Won’t be long before Leo’s bigger than me.”

A second wrote: “Your son is the double of you!”

“Woohoo! Huge congratulations to both of you for those pull ups…no small feat! And happy 50th! Hope the celebrations were nothing short of amazing,” said a third.

While a fourth commented: “Gosh you can see both you and Annie in Sam.”

Ben also has another teenage son called Jack with his wife Annie.
