How old were the soldiers trained in Athens how old were soldiers trained in Sparta?

In Athens, young boys began their military training around the age of 18 as part of their education, which included a focus on civic responsibility and culture. In contrast, Spartan soldiers, known as hoplites, started their rigorous training in the agoge system at the age of 7, continuing until they were about 20, when they became full-fledged soldiers. This early and intense training in Sparta was designed to create disciplined and skilled warriors.
