About the Muscle Fiber Strand black outline icon
A long spindle-shaped strand tapers to pointed tips at both ends, with three curved internal lines suggesting the striated bundles that run along a muscle cell. It stands for tissue structure, contraction and physical strength at a cellular level, making it suitable for anatomy and biology e-learning, fitness and recovery apps, physiotherapy clinic pages, sports science slides and supplement product diagrams.
The form sits on a 45-degree diagonal, with concave outer edges giving the classic muscle-belly bulge and the inner strokes following that curve so the strand looks twisted rather than flat. Consistent thin lines keep it light next to heavier icons. It pairs with bone, joint and dumbbell icons; use 40 px or more so the striations remain separate.
This is the black outline version of the muscle fiber strand icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
