Rebecca Judd flaunts super toned body in black, cleavage-baring bikini

The AFL Wag rarely posts bikini photos online but whenever she does it often leaves her nearly one million Instagram followers asking one question.

The moment Bec Judd shared a photo showing off her incredibly toned body in a low-cut bikini, it was inundated with comments from baffled fans.

The 37-year-old model and TV presenter posted the snap on Instagram on Thursday to spruik a her co-owned fake tanning product Spray Aus, but her almost one million followers could not help but notice how “amazing” she looked “after four kids”.

“Does the body come with it,” one fan joked.

“The colour (and you!) looks amazing!,” said another.

“Absolutely gorgeous,” a third person wrote, while a fourth said she was the “next Elle (McPherson)”.

Others were blown away by her youthful looks, saying, “I can’t believe you have had four kids”.

“Four kids, working mum – How do you never look tired?” another asked, while a third woman simply wrote, “After kids wow”.

Bec — who has four children, aged from three to nine, with her husband, AFL star Chris Judd — does not often share bikini photos to her Instagram page. The last time was in December and January this year — but again, on both occasions, followers inundated her posts with a slew of positive comments.

“Stop it you big babe,” celebrity stylist Lana Wilkinson wrote on of the photo’s of Bec posing poolside.

“Great arms!” another fan added.

Bec revealed she plays four hours of tennis to keep fit and healthy.

“I am addicted to cardio tennis, I play for two hours twice a week because it’s really fun,” she told news.com.au in July last year.

“There’s no serving. It’s a cardio workout where the music blares, the coach just feeds you balls, you do awesome drills with lots of running, and it’s 60 minutes that goes so quickly.”

Bec, who is the co-owner of fitness company Jagged and hosts the 3PM Pick-Up on KIIS FM, said between juggling work and family, she trains for two hours twice a week.
