Josh Brolin's wife Kathryn Boyd shows off bare baby bump as she hits the gym in black leggings

She may be a heavily pregnant successful model married to one of Hollywood's top stars, but that hasn't stopped her from still focusing on her fitness.

On Saturday, Kathryn Brolin (nee Boyd) posted a photo on Instagram that showed her hitting up the gym for the first time in a couple of days.

The 30-year-old appeared makeup free and stunned in a form-fitting active wear set as she flaunted her growing baby bump.

Kathryn opted for a black shirt that showcased her burgeoning baby bump.  

She paired the look with figure-hugging yoga pants and a pair of matching sneakers.

The soon-to-be first-time-mom opted to go makeup free and had her blonde locks styled back into a high ponytail.

The photo was snapped in her home gym and she admitted that she hasn't been working out like she should be.

'Took some time to make the rounds with my beloved family and dear friends in Atlanta for a couple weeks and honestly didn't focus on working out nearly as much as I should've,' she captioned the shot shortly before making her entire Instagram private.

The actress went on, 'Finally getting back in the swing of it as we chart through this last trimester (whaaatttt). This was three days and I'm still recovering from the soreness that resulted.'

'Grateful for this functioning and amazing body of mine and seeing all the miraculousness programmed in it to grow this baby. So incredibly grateful for this experience and that my body can handle it. Recommitting to working out and staying active every day to keep strong both physically and mentally,' she concluded.

The 5'10" statuesque model is just weeks away from expecting a baby girl with her Hollywood star husband Josh Brolin, 50. It's unclear why she decided to not share her social media page publicly any more.

The actor already has two adult children Trevor, 30, and Eden, 25, from his first eight year marriage to actress Alice Adair.

He also wed Diane Lane from 2004 to 2013, but the couple did not have kids.

Speaking to Us Weekly back in June regarding the baby news, the Deadpool actor revealed he was excited.

'I'm nervous, but excited,' he said.

'I've been a parent for so long, since as long as I can remember basically. I got out of high school, two years later we had a kid. So I don't really know life without having kids.

He added that he was 'massively looking forward to' meeting his little girl.

Josh and Kathryn wed in 2016.
