“Whether domestic or civic duties occupy you, keep some time of the day for caring for the body. The chief way of caring for the body is exercise and it should always be done before eating. The work should be greater for one who has labored less and digested well and less for one who is tired and has not digested. Good exercises include reading aloud, drilling, playing ball, running, walking. The last is not the most useful on a level road, since going up or down moves the body with a variety, unless the body is completely weak. It is better to walk out in the open than under a roof. And it is also better, should your head endure it, to walk in the sun instead of the shade. But better still in the shade than under a roof and better a straight than an indirect walk.
The end of exercise, moreover, should come with sweat or some bit of tiring which should still be on this side of fatigue. Sometimes more and sometimes less needs to be done. But one should not follow the model of athletes with their fixed rule and excessive workout.”
Quem interdiu vel domestica vel civilia officia tenuerunt, huic tempus aliquod servandum curationi corporis sui est. Prima autem eius curatio exercitatio est, quae semper antecedere cibum debet, in eo, qui minus laboravit et bene concoxit, amplior; in eo, qui fatigatus est et minus concoxit, remissior.
Commode vero exercent clara lectio, arma, pila, cursus, ambulatio, atque haec non utique plana commodior est, siquidem melius ascensus quoque et descensus cum quadam varietate corpus moveat, nisi tamen id perquam inbecillum est: melior autem est sub divo quam in porticu; melior, si caput patitur, in sole quam in umbra, melior in umbra quam paries aut viridia efficiunt, quam quae tecto subest; melior recta quam flexuosa. Exercitationis autem plerumque finis esse debet sudor aut certe lassitudo, quae citra fatigationem sit, idque ipsum modo minus, modo magis faciendum est. Ac ne his quidem athletarum exemplo vel certa esse lex vel inmodicus labor debet.
Hippocrates, Regimen 2 61
“I will now explore what kind of impact exercises have. For some are natural and some are pretty violent. Natural exercise deals with sight, hearing, voice, and thinking. The power of sight is like this. The soul, when it attends to what can be seen, moves and warms. As it warms it dries because the moisture is extracted. In hearing, when sound strikes, the soul shakes and works and as it exercises, it turns warm and dries.
A person’s soul is moved by however many thoughts it has and it also warms and is dried and it spends its moisture as it works—it can empty the flesh and make a person thin. Whenever people exercise their voice either in speaking,reading or singing, all these things move the soul. When it is moved, it warms and dries and uses up the moisture.”
Περὶ δὲ τῶν πόνων ἥντινα ἔχουσι δύναμιν διηγήσομαι. εἰσὶ γὰρ οἱ μὲν κατὰ φύσιν, οἱ δὲ διὰ βίης· οἱ μὲν οὖν κατὰ φύσιν αὐτῶν εἰσιν ὄψιος πόνος, ἀκοῆς, φωνῆς, μερίμνης. ὄψιος μὲν οὖν δύναμις τοιήδε· προσέχουσα ἡ ψυχὴ τῷ ὁρατῷ κινεῖται καὶ θερμαίνεται· θερμαινομένη δὲ ξηραίνεται, κεκενωμένου τοῦ ὑγροῦ. διὰ δὲ τῆς ἀκοῆς ἐσπίπτοντος τοῦ ψόφου σείεται ἡ ψυχὴ καὶ πονεῖ, πονέουσα δὲ θερμαίνεται καὶ ξηραίνεται. ὅσα μεριμνᾷ ἄνθρωπος, κινεῖται ἡ ψυχὴ ὑπὸ τούτων καὶ θερμαίνεται καὶ ξηραίνεται, καὶ τὸ ὑγρὸν καταναλίσκουσα πονεῖ, καὶ κενοῖ τὰς σάρκας, καὶ λεπτύνει τὸν ἄνθρωπον. ὁκόσοι δὲ πόνοι φωνῆς, ἢ λέξιες ἢ ἀναγνώσιες ἢ ᾠδαί, πάντες οὗτοι κινέουσι τὴν ψυχήν· κινεομένη δὲ θερμαίνεται καὶ ξηραίνεται, καὶ τὸ ὑγρὸν καταναλίσκει
