How to use this prompt

"Thick clean white iconography" against the gradient is the small-size trick: at 60 pixels a thin-stroke dumbbell disappears, and white-on-gradient holds contrast wherever the eye lands on the color sweep. Fusing the heartbeat line into the dumbbell bar keeps it one mark — phrase them as two objects and Midjourney draws a gym still-life instead. Keep stylize at 100; higher and MJ starts adding chrome, bevels, and particle effects that break the flat language. The --no list earns its length here because MJ badly wants to mock this up on a phone screen with a hand holding it.

Variations to try

  • Run tracker — "a single simplified running-shoe side profile with a pulse line through the sole" keeps the energy
  • Cool palette — swap the background for "electric blue to lime green gradient" for a sports-drink read
