A few years ago I tried out TikTok and quickly came to see that there are huge niches inside the platform that are barely even searchable or existent outside the app. One of which was these videos of people sprinting or galloping on all fours. It's fascinating and terrifying seeing people who've practiced do the movements, it's uncanny in both how natural and unnatural it can look. It seems to be an intersection of unconventional exercise enthusiasts and furry-types.

Very cool! Reminds me of Tim Burton's "Planet of the Apes" (2001), which did quadrupedal running with practical effects — harnesses, towed treadmills, all sorts of tricks — i.e., cheating, from the POV of this thread. :)
"Behind the Scenes of Tim Burton's Planet of the Apes": https://www.youtube.com/watch?v=KighzjHkZtY&t=803s "Ape School" starts at 9m35s. Quadrupedal running starts at 13m23s.
