Sunlight streamed through the gaps in the curtains, dispelling the remnants of the night.
With the continuous "whoosh whoosh" sounds in the air, the mottled light and shadow swayed as if dancing spirits.
A muscular figure was practicing Air Attack in the cramped bedroom, throwing punches with vigor and strength.
As he punched, veins on his arms bulged like a drawn bowstring, and one could hear the roaring sound of Strength surging and gathering within.
When kicking, his leg muscles bulged like a tightly wound spring suddenly releasing, kicking up a leg and causing the air flow to abruptly lift the curtains high.
Under the morning light, the muscles that seemed forged from refined steel appeared even more pronounced and sharply defined.
As he moved, his muscles undulated and contracted like waves, flowing smoothly and naturally.
It was as if this was a silent symphony of Strength and beauty.
