EW's editorial guidelines Published on March 9, 2018 01:51PM EST Kevin Hart is on a mission to work out hard with celebrities, even if said celebrities aren’t as enthusiastic about it all. The new Kevin Hart: What the Fit trailer shows the kinds of situations the comedian will get into with the likes of Conan O’Brien, Tiffany Haddish, Bill Hader, Khloe Kardashian, and Chance the Rapper for his new series coming to YouTube. “We’re taking physical fitness to another level — doing different things, challenging ourselves,” Hart says. This means we’ll get to see the Jumanji: Welcome to the Jungle star try sumo wrestling with O’Brien, beer yoga with Chance the Rapper, goat yoga with Kardashian, body building with James Corden (and his eye-popping short selection), fire fighting with Niecy Nash, ballet with Ken Jeong, and Daddy and Me classes with DJ Khaled. O’Brien had actually previewed his sumo stint on Conan earlier in the week. “When he took his shirt off, we were like, ‘Wow! That’s what it looks like, huh?'” Hart joshed the late-night host. “That’s where a lot of the laughs came in. And remember we took a break because we were laughing so hard.” Other celebrities featured in What the Fit are Scott Eastwood, Joel McHale, Leslie Jones, and Jack Black. The original YouTube series, produced through Hart and Lionsgate’s Laugh Out Loud network on YouTube, will premiere on March 15. New episodes will air twice a week on Thursdays and Fridays.
