You might think, well, how much does Bryan Ropar know about whips, though? Would Indiana Jones have drawn his own blood?
Yeah, he probably would. Ropar is a prolific YouTuber with many channels including one dedicated to his plastic chair collection and one specifically dedicated to "bullwhips, knives, axes, bows, and rifles." (That's a different channel than where the above video comes from. That channel appears to be dedicated to backyard experiments he builds but rarely shows in action.)
Watching a few bullwhip instructionals, it becomes apparent that he knows what he's doing (or he's doing some tricky editing). Either way, he's not unfamiliar with cracking bullwhips and you should probably steer clear of a monstrous one like this. As Ropar says, "That is by far one of the stupidest things I've ever done in my life. I think I was muscling it way too hard."
