Rob Kardashian is getting his workout on, and he’s seeing some familiar faces in the neighborhood.

The 28-year-old son of Kris Jenner and Robert Kardashian was working out in sunny Southern California on Monday (Aug. 24) when he spotted sister Kylie Jenner and her boyfriend Tyga on the other side of the street. He posted the run-in to Instagram, captioning it, “Spotted these fools on the morning workout.”

Kardashian has been open about his struggles with his weight in the past, but seems to be in a workout groove. Sister Kim Kardashian posted earlier in August that the pair had gone on “the hardest hike ever.”

Earlier in 2015 Kardashian confronted his weight critics with a throwback photo of him in high school.

“Last throwback of the day and yes I’m fat now so y’all haters can literally suck d***,” he wrote in February.
