When you sculpt, you take stone, wood, clay, ice, or something like that and slowly make it into a shape — a face, an animal, a figure. You cut, press, and smooth until the shape is there. That is the home meaning: an artist's hands and tools. Though actually, people stretch it a lot. In the gym, you sculpt your arms or stomach, meaning you train until the shape looks clear and strong. A hairdresser may sculpt a haircut; a cook may sculpt food. It still means “give a careful shape,” not just “make.” Sculpt is mostly the action. The finished thing is usually called a sculpture. The word is fine in art class and in writing; the body meaning is informal gym talk.
