About the Muscle black outline icon
A spindle-shaped muscle belly drawn on a diagonal, its interior filled with parallel striations and tapering at both ends into straight tendon lines. Rather than a flexed arm, this is the tissue itself, which makes it fit anatomy diagrams, physiotherapy and sports medicine sites, fitness tracking apps, supplement packaging and biology teaching slides.
Two straight lines run in from opposite corners as tendons, meeting a lens-shaped belly whose inner strokes sit at a slant to suggest fibers. It sits alongside bone, joint and heart icons; at small sizes the thin striations merge, so keep it above 32 px.
This is the black outline version of the muscle icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
