Los Angeles, California - Kylie Jenner got real about the pain she's experienced since giving birth to her son.

While the world still awaits Kylie's son new name – since announcing and then changing it – the reality-star is making strides in her fitness journey.

On Monday, the 24-year-old billionaire updated fans via her Instagram story, where she shared clips of herself in the gym.

"No days off!" Kylie captioned in a mirror selfie, in which she was seen posing in a matching brown sports bra and spandex set.

In another snap, The Kardashians star also shared that she had been experiencing pain after giving birth to her baby boy.

"4 months postpartum," Kylie wrote in the next shot, where she's seen on a treadmill.

"I have been dealing w tons of back & knee pain this time, so it slows down my workouts, but I am on a mission to get strong again."

Get it, Kylie!

The Kylie's Cosmetics owner has been very open about her postpartum recovery struggles following the birth of her second child with partner Travis Scott.

Back in April, Kylie revealed that she gained 60 lbs during her second pregnancy, which she also explained was more difficult than her first one.

Despite this, the hot mama has wowed in her recent snaps. Particularly, with risqué bikini pics she shared last week.

But what the world is still dying to know is what Kylie's baby boy's new moniker will be.
