An Olympic athlete must be strong not only in body, but also in mind. They have to train for years to achieve the necessary strength and control over their sports to compete in the Olympics. This requires great discipline and self-sacrifice. Similarly, the Olympic athletes have to train their minds in order to compete under extreme mental pressure. In other words, and Olympic athlete must be in top condition both mentally and physically.
