Bec and Chris Judd are thrilled with their happy family

If you take one look at super fit Rebecca Judd, it's hard to believe that she gave birth to twins just five weeks ago.

And on top of that, she and husband Chris have in fact welcomed four healthy babies in five years.

The 33-year-old AFL WAG and her hubby are just as pleasantly surprised as us, with Bec telling her Instagram fans: “We weren’t expecting that when we started out”.

They're already parents to five-year-old Oscar and two-year-old daughter Billie.

Taking to the social media platform, Bec shared a photo of her and Chris visiting the Melbourne hospital where she gave birth to all four of her children.

“Big shout out to the best Obstetrician in the world (and loveliest man) Dr Len Kliman and the awesome@midwifecath for delivering me 4 healthy babies in 5 years,” she captioned the group photo which featured her children and the hospital staff.

“We weren't expecting that when we started out. These guys make an incredible dream team and I can't recommend them enough.”

Last week Bec slammed slammed critics who questioned her decision to return to the gym four weeks after giving birth to the twins via c-section.

Although some health professionals recommend six weeks of healing before returning to regular work-outs, the media personality shared a snap to Instagram of herself back in the gym.

"A HUGE shout out to Shira Kramer and her team of women's health physiotherapists at @beactivephysio for keeping me fit and strong during my pregnancy (all 3 of my pregnancies actually)," the TV presenter wrote alongside the image of herself mid-workout.

"I did clinical Pilates and pre-natal exercise classes 2-3 times a week and credit them with the fact that I'm feeling great, have a strong core, minimal ab separation despite measuring 47 weeks the day I delivered the twins (!!!) and have recovered well.

"Thanks for the visit today Shira and I promise not to bump up the reformer resistance or go fast on the spin bike when you're not here keeping watch!"

Taking aim at haters who questioned her decision to seemingly defy doctor's orders and return to her workout routine early Bec added, "ps. And yes, of course we checked with obstetrician first”.

Go Bec, you do you!
