Hailey Bieber gives a glimpse of tough postpartum workout after Jack first birthday.

Hailey Bieber has given fans an inside look at the demanding postpartum fitness routine she’s been following, nearly a year after welcoming her son, Jack. On Saturday, the founder of Rhode took to Instagram to offer a rare look into her workout regimen following the birth of her first child.

In the video she shared, Hailey is seen wearing a sports bra and biker shorts while engaging in a tough workout. Hailey, who has previously spoken about dealing with postpartum body dysmorphia, posted a black-and-white clip of her exercising, set to “SPEED DEMON,” a track by her husband, Justin Bieber.

The workout appeared to take place in her personal home gym, where she was shown doing crunches with the aid of a yoga block and mat. Her latest post comes shortly after she and Justin marked their son Jack’s first birthday. Hailey gave a shout-out to her trainer, Kirsty Godso, tagging her in the video and referencing a move they both favor: “our fave rib flare exercise.”

She added that she “did lots of these to help correct rib flare after pregnancy.”

Earlier this year, Hailey opened up about her experience navigating pregnancy, childbirth, and postpartum recovery for the first time.

In a candid interview with Vogue, she described it as the “most sensitive time I've ever gone through.” She revealed how emotionally intense the journey was, sharing that she felt both “high highs and low lows,” and faced unexpected feelings of “self-hatred” as her body changed during and after pregnancy.

“Every day I have to talk to myself, like ‘Hailey, you had a baby. You grew a human. You birthed a human. It's okay. Give yourself grace. Give yourself time,’” she said at the time.

Hailey admitted that shedding the last 15 pounds of baby weight took more time than anticipated. She worked closely with health professionals on foundational recovery, focusing on areas like core strength, spinal alignment, and pelvic floor rehabilitation.

Hailey and Justin Bieber became parents to their son, Jack Blue Bieber, on August 28, 2024, and have been embracing their new chapter as a family ever since.
