This is FigureRobics, a Chinese workout-video series in which they count to eight in English over and over. I've looked at several of these videos, and in all of them the counting is a central feature. It's really the only distinguishing feature, other than consistently good hairstyles for both the male and female performers.
I have an opinion about counting to eight over and over in workout videos: it's repetitive, depressing, and cultish. Like, yeah, existentially we're all just ticking away the eight-counts until we leave this world (of sass), but must you be so literal about it? Billy Blanks does it with his crew in his early Tae Bo videos, and the counting is definitely framed as an expression of zealotry—a titillating, ritualistic way to show how ALL IN they are—but I think they cut it out after the warm-up. Either that or I learned to tune it out, because the background music wasn't too bad and I could focus on that. Here, all you've got is a lonely high-hat house loop, evoking a hiccuping kitchen clock.
I was excited to do my first Chinese workout video, and these floor exercises seem fine, but yeah no.
