After becoming a mother of two, The Kardashians star Kylie Jenner is working hard to rebuild her strength and body. 

There is no gain if there is no pain! So in the months since welcoming her newborn son, Kylie has made significant progress in her fitness journey.

On Monday, June 13, the 24-year-old reality star shared some clips from her postpartum transformation on her Instagram Story as she hit the gym despite recent knee and back issues.

"No days off!" Kylie captioned a photo of herself in activewear as she shared a peek into her workout routine.

While the "No day off" photo of Kylie may look like she's already got her body back, she previously admitted she has not been having it easy at the gym.

"I have been dealing w tons of back & knee pain this time so it slows down my workouts," she wrote alongside a video of herself on the treadmill, "but I am on a mission to get strong again," she captioned the video.

Kylie has been recording her workouts since she and Travis Scott welcomed their second child a few months ago. She shared a photo of her core in April, writing, "My abs over here trying to make a comeback finally." As for her go-to exercise routine, the makeup mogul shared later that month that it is a combination of walking and Pilates.

"Gained 60lbs again this pregnancy," Kylie also wrote alongside a black-and-white shot of herself walking on a treadmill before she detailed that she is currently "down 40lbs 🙏🏻."

Kylie and Travis are also parents to 4-year-old daughter Stormi Webster.

Kylie's postpartum journey shows she has been kind to herself as she regains control of her body. As a result, she encouraged other parents to treat themselves with the same kindness.

"It's not easy mentally, physically, spiritually," Kylie said. "It's just crazy and, yeah, I didn't wanna just get back to life without saying that because…we can go on the internet and it might look a lot easier for other people and put the pressure on us but it hasn't been easy for me either. It's been hard, and I just wanted to say that."

The socialite also reminded her followers that it's okay not to be okay, as she shunned unnecessary pressure after birth. 

"I was putting some pressure on myself and I just keep reminding myself I made a whole human, a beautiful healthy boy," she continued, "and we have to stop putting on ourselves to be back, not even physically just mentally, after birth."

The Kardashians star's numerous fans are proud of her and applaud her for being so open about her postpartum experiences.
