Model Ashley Graham's intense pregnancy workout sparks strong opinions from fans

Supermodel and body positive advocate Ashley Graham is no stranger to tough workouts, and the 31-year-old is showing no signs of slowing down since announcing her pregnancy back in August.

The Sports Illustrated cover star, who expecting her first child with husband Justin Ervin, took to Instagram on Tuesday to share a video of herself working up a sweat in the gym.

In the clip, a lycra-clad Ashley can be seen smashing out set after set on a vertical rowing machine and the intensity of the routine wasn’t lost on many of her 9.2 million followers.

Ashley’s baby bump workout

Throughout the session, Ashley’s trainer, celebrity coach Kira Stokes, can be heard offering up encouragement, saying, “That’s it, Ashley, breathe. Gotta get that conditioning work in”.

Kira shared a few more images in her Instagram stories, showing her client working on a weight machine, with the caption, “STRONG BACK = posture on point”.

At the end of her heart-rate raising set, the beaming mum-to-be gives her belly a cute little pat. But it appears to be all in a day’s work(out) for the catwalk star, who captioned the video, “It’s a lifestyle”.

Fans, however, shared their concern for Ashley’s activity in the comments, with one urging her to “Be careful!”

“Careful with the baby girl,” added one, while another said, “Relax and take a break”.

“This scares me,” admitted one, but another came to Ashley’s defence, saying, “as long as she’s not overdoing it, it’s ok”.

“If she was doing all that before she got pregnant (which she was) it’s totally okay to do it while pregnant” added another.

Praise for Ashley

Elsewhere in the comments, Ashely’s followers and celeb friends weighed in with praise for the soon-to-be-mama.

Actress La La Anthony gave her a big “Yesssss‼️‼️‼️” and Olympic athlete Lindsey Vonn dropped a “100%!!” followed by flexing arm emojis.

“Yes sis! Such an inspiration and absolutely love your commitment!!!” wrote a fan, while another called her “Warrior!!!”

“Absolutely gorgeous momma! I aspire to be like this next pregnancy because this one is uncomfortable,” shared another.

And there were more than a few people sharing this simple sentiment: “GET IT MAMA.”

“I can't even do that without another human growing inside of me” joked one.

Ashley has been a source of inspiration throughout her pregnancy, staying fit and active at the gym and with her yoga practice.

She also kicked off New York Fashion Week in a skintight, red latex dress that put her burgeoning belly on show.

And in August, she made a bold statement for body positivity by baring all - down to every last ripple and shimmering stretch mark - in a photo posted to Instagram.
