# Muscle diagram overlay shows what each move hits

A fitness format, measured November 8, 2026 by Volume. https://tryvolume.app/working/fitness/muscle-diagram-overlay-shows-what-each-move-hits

Anatomy graphics, glowing muscle overlays or colour-coded diagrams sit next to each exercise so the target muscle is visible at a glance. It worked for 21 accounts, with a median of 6x their usual reach. Type: Editing trick. Seen as: Talking head, Slideshow, Video, Voiceover.

## Why it works

The graphic proves the move works and shows what it targets without any explanation. Posts from Homegainlab, Rauvesuave, Yourfitnessmom, Joinyoucan and Justin Agustin pair the demo with a highlighted muscle.

## How to make it

1. Show the exercise demo
2. Add an anatomy diagram or row of muscle icons
3. Highlight (red glow, colour or checkmark) the active muscle as it works
4. Keep the diagram on screen for the whole move

## Hook formula

One move. [NUMBER] muscles worked.

## How this is measured

- Every post is compared with its own account's usual reach, not with other accounts. "14x their usual" means the post got 14 times the median views of that account's recent posts.
- TikTok videos and Instagram Reels are measured on views. Instagram carousels have no view count, so they are measured on likes against the account's usual likes, and say so.
- A post makes the library at 2x its account's usual or more. A format is a repeatable move (what is said or shown, or how it is edited) that several accounts used in breakout posts. It is listed here once it worked for 3 or more different accounts.
- Formats rank on how many accounts they worked for and how far above usual, damped so a fluke on one tiny account cannot outrank a format that worked for ten.
