About the Muscle Fiber Strand black filled icon
Two curved lines taper to sharp points to form a spindle-shaped muscle belly, with an inner arc and a straight diagonal strand running through the middle of the fiber. The shape stands for strength, training and physical effort. Use it in gym apps, workout trackers, physiotherapy sites, anatomy lessons and sports nutrition labels.
The abstract, elongated form reads as muscle tissue rather than a flexed arm, so it suits clinical and fitness contexts alike, and the diagonal placement fills the square frame evenly. It pairs with dumbbell, bone and joint icons; add a label in medical use.
This is the solid black filled version of the muscle fiber strand icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
