Schwarzenegger came out of retirement, however, to compete in the 1980 Mr. Olympia.
Schwarzenegger was training for his role in Conan, and he got into such good shape because of the running,
horseback riding and sword training, that he decided he wanted to win the Mr. Olympia contest one last time.
He kept this plan a secret, in the event that a training accident would prevent his entry and cause him to
lose face. Schwarzenegger had been hired to provide color commentary for network television, when he announced
at the eleventh hour that while he was there: "Why not compete?" Schwarzenegger ended up winning the event
with only seven weeks of preparation. After being declared Mr. Olympia for a seventh time, Schwarzenegger then officially retired from competition. -Wiki-
