Who gives Hercules his strength?

Hercules, in Greek mythology, is granted his incredible strength by his divine father, Zeus. However, his strength is often portrayed as a result of his demigod lineage, being the son of a god and a mortal woman, Alcmene. Additionally, some myths suggest that his strength is a gift from the gods, enabling him to complete his legendary Twelve Labors. Ultimately, his strength symbolizes both his heroic capabilities and the challenges he must overcome.
