D. What Exercise is requisite? C. Not too easy, nor too vehement; not too swift, nor too slow; but moderate. However the Phlegmatic require a stronger and violent Exercise then the Choleric. Equality in Exercise is preferred before Inequality: And that Exercise which most delights the Mind, ought to be looked upon as the most wholesome. D. How long is Exercise to be continued? C. Till the Body grow warm, and a lively Color appear in the Countenance, together with a Sweat mixed with a hot Vapor; till the Respiration be large, yet easy; and while the Motion continues equal and brisk. While and of these fail, ‘tis time to desist, lest the Body grow colder, drier and leaner with long exercise: But always let the exercise of the person be answerable to his Food; for the more liberally or sparingly a man feeds, the more or less he ought to exercise. D. What is the method of Exercise? C. Exercise is requisite as often as the Body is fed; a gentle motion at first, then more vehement, then more gentle again. D. What time is most fit for Exercise? C. When the Concoction is perfected. But in regard that Exercise stirs up the Natural Heat, without which the Meat cannot well be concocted; Exercise ought to be always used before Meals: Besides that, Exercise consumes many Superfluities, which are first to be expelled, before any more Nourishment be received in. After Meals Exercise is hurtful, in regard the agitation of the Body joggs down the Nourishment out of the Stomach where it be concocted, which occasions several Crudities in the Veins, that beget several Diseases. Neither is a man to exercise, till he has emptied his Body of such Excrements as call upon Nature, lest any thing of them be carried away into the Habit of the Body, through the force of the Natural Heat redoubled by Exercise. Previous: Of Sleeping and Waking Next: Of Rest

Natural Heat: Yang Exercise helps consume excesses that are not properly digested Crudities: undigested Humors
