Mens sana in corpore sano
Mens sana in corpore sano is a Latin phrase, usually translated as "a sound mind in a sound body" or "a healthy mind in a healthy body".
In the western world, the phrase is widely used in sporting and educational contexts to express the theory that physical exercise is an important or essential part of mental and psychological well-being.
