Both spartan boys and girls received

Both Spartan boys and girls would receive physical training. The boys would train to be soldiers and eventually, when they would turn 20 they would become full-time soldiers.

Women would mostly learn different combat skills and gymnastics, they thought that if a woman were healthy, they would also make healthy children.
