Kylie Jenner is keeping fans up-to-date on her postpartum fitness journey.

Four months after giving birth to a baby boy, the 24-year-old shared a glimpse into her workout routine, captioning the shot of her in activewear, “No days off!” However, it wasn’t the easiest gym session for The Kardashians star. “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.” 

Kylie has been documenting her workouts for the past few months since she and Travis Scott welcomed their son. She posted an April photo of her core and wrote, “My abs are trying to make a return finally.” As for her go-to exercise routine, the makeup mogul shared later that month that it’s a combination of walking and Pilates. 

“Gained 60 lbs again this pregnancies,” she said at that time. “Down 40 lbs just trying be healthy and patient.”
