Video prompt: The sun glints off the polished metal of the hammer as he swings it in a wide arc, his muscles rippling with the effort. As he releases the hammer, it soars through the air, spinning gracefully against the clear blue sky.

The crowd erupts into applause, a wave of sound that washes over him as he stands tall, a triumphant smile spreading across his face. The hammer lands with a thud in the distance, marking a new personal best.
