As noted in the YouTube description:
WWE World Heavyweight Champion Triple H and WWE Hall of Famer Arnold Schwarzenegger answer questions at the 2016 Arnold Sports Festival in Columbus, Ohio.
WWE has a heavy presence at the Arnold Sports Festival each year with NXT and Arnold, a WWE fan, takes the opportunity to hang with his ol' pal Triple H. There's actually a point in the video where they stop what they're doing so they can make a Snapchat video.
What a time to be alive.
