Rob Kardashian is working off that weight once again. With a baby on the way and a successful reality show on TV, according to TMZ, the sole Kardashian brother is ready to get back into a healthy state of mind and body. In a video taken from Kourtney Kardashian's Snapchat, Rob can be seen working a CrossFit-style workout with both Kourtney and Khloe. Medicine balls and all.

From the sounds of it, Rob and the Kardashian clan bump Lil Yachty and Rihanna when they work out. In the video below, RiRi's "Needed Me" and Yachty's verse on "Broccoli" can be heard. We're happy for Rob.
