Rounded-square modern fitness app icon with a bold, minimalist silhouette of a person in mid-run, composed of clean geometric shapes. Centered figure leaning forward to convey speed, with subtle motion lines. Background features a smooth gradient from electric teal to deep blue for a lively, modern look. Flat vector design, crisp edges, no textures or shadows; high contrast to stay legible at small sizes; no text. Overall style is contemporary, geometric minimalism, distinctive yet simple, scalable for app stores.

The image shows a black and white icon of a man running with a white background. The icon is in the center of the image and is surrounded by a white border.
