Running is my Cardio - RIMCDO01 Tシャツ

The centerpiece of the design features three overlapping silhouettes of a runner in full sprint. These figures are rendered in various shades of vibrant green, ranging from a deep forest green to a bright neon lime. The runners feature a striking "dissolving" or "pixel-dust" effect trailing behind them. This creates a powerful sense of motion and speed, as if the athlete is moving so fast they are blurring into the atmosphere. The phrase "RUNNING IS MY CARDIO" arches elegantly over the figures in a clean, white, bold sans-serif font. The curved text mimics the top of a circular badge or a finish-line emblem. The entire scene is set against a soft, light-gray circular backdrop, which focuses the eye and gives the design a finished, "sticker" or "logo" feel. The palette is a fresh combination of athletic greens and crisp whites, evoking health, stamina, and energy.
