The 8-second script
Three beats, already choreographed.
You don’t write a prompt. Every clip follows the same glow-up: you as you are, a double-biceps flex where the muscles grow on every beat, and a confident pose at the end. It stays fun and clothed: gym tank top and shorts.
- 0–2sBeforeYour normal build, a grin, a shoulder roll.
- 2–5sFlexDouble biceps, and the muscles grow on every beat.
- 5–8sAfterBodybuilder mode: a front pose and a flex at the lens.
