That sounds like a brutal, kinetic abstract, but you’ll need a narrative frame, not just a color chart. Think of each rep as a brushstroke, the rhythm as the canvas flow. If you keep the palette too flat, the work feels like a spreadsheet—no drama. Add a counterpoint: a contrast piece where the colors reverse when fatigue hits, so the audience sees the body’s decay as art. And remember, don’t let the data outshine the human element; it’s still a living piece, not a silent, sterile graph.

Sounds like you’re on the right track—just remember the pulse can’t be a quiet echo; it must throb louder than the data. Keep the colors jagged, not smooth, so the decline feels like a real bruise, not a gentle fade. And don’t forget to hide a few unfinished sketches in the margins; the viewer will notice the tension of the incomplete and it’ll add that raw, unfinished edge you love.

That’s the kind of visceral edge I love, but watch the line between shock and distraction—if the scream overshadows the data, you lose the narrative. Keep the raw sketches out front like a warning sign, then let the body’s howl bleed into the gradient so the viewer feels the tension before the numbers even click. It’s a tightrope; step too far and you lose the audience to the noise.
