Hailey Bieber reveals secret to her bikini body as she shares rare look at workout routine

Weeks after amazing fans with her bikini body, Hailey Bieber is giving fans a rare glimpse into her grueling workout regimen.

On Saturday, the 29-year-old model took to her Instagram Story to share a short clip of herself working out with celebrity fitness trainer Kirsty Godso.

Hailey, who is the wife of singer Justin Bieber, performed dumbbell hip thrusts while holding herself up off of the ground between two benches.

Over the video, she wrote that she was in the midst of a 'Saturday a** kick' with Godso, who boasts over 380,000 followers on Instagram.

The Rhode founder also set the video to the tune of Don Toliver's song Call Back. 

For her workout, Hailey wore a light gray sports bra paired with figure-hugging yoga pants and white sneakers with black laces.

Hailey's latest Instagram post comes just days after she revealed her pregnancy with her son Jack Blues Bieber, who is now 19 months, was a 'surprise' for her and Bieber.

While making an appearance on the SHE MD podcast, she discussed her pregnancy and postpartum experience.

Hailey was chatting with podcast hosts Mary Alice Haney and Dr. Thaïs Aliabadi, who happens to be Hailey's obstetrician-gynecologist (OBGYN).

On their podcast, Hailey recalled a story about how she was diagnosed with a medical condition that can cause pregnancy complications right before learning that she was pregnant. 

Hailey was asked if she and Justin were 'trying' or if their baby was a 'surprise.' 

Referring to her personal physician, Hailey shared: 'It was a surprise. She told me this was going to happen because she was like...'

Dr. Aliabadi chimed in: 'And I told her, like, "Don't get pregnant!"'

She said that her OBGYN had diagnosed her with uterine septum, a genetic condition, as she explained: 'I had a septum in my uterus, and Dr. A kept saying, "Well, we need to look at this and keep an eye on it before you get pregnant because it could potentially be an issue..."'

Hailey continued: 'And I was like, "OK. Well I'm not thinking about getting pregnant right now, so we'll just cross that bridge when we get there." And then I magically got pregnant.'  

Dr. Aliabadi confirmed: 'Your [uterine septum] was moderate. It affects one to three percent of women, and with moderate, you have a higher risk of miscarriage with the pregnancy.'

This comes after Hailey admitted 'giving birth was the hardest thing I've ever done' as she opened up about her difficult birth story in a Vogue interview published last year.

After prepping with acupuncture, breathing techniques, yoga, and pelvic floor therapy, she told the outlet: 'I felt stronger physically than I ever had before.' 

However, she was caught off guard when she experienced a postpartum hemorrhage. 

For her May 2025 cover story, she told the magazine: '[It] was a little bit scary, [but] I trust my doctor with my life. 

'And so I had peace that I knew she would never let anything happen to me. But I was bleeding really badly, and people die, and the thought crosses your mind. You start to get a little freaked out.' 

She also told the outlet: 'Being postpartum is the most sensitive time I've ever gone through. And to be doing that all the while going on the internet every day…I cannot even begin to explain it.'
