How To Run (1657)
from Ask the Past*

Running, if it be vehement, is good for fat and moist bodies, but it is bad for such as are troubled with any kind of headache.

If running be moderate, it excellently warms the body, excites appetite.

Uphill, 'tis bad for the breast and thighs. Downhill it very much affects the head, it shakes the bowels, troubles weak hips.

The body being covered, by moving sweat, it moistens and heats the flesh, but it makes the bodies ill-colored, because the pure air does not come at them, to cleanse the same.

The body being naked, it draws out great plenty of sweat.
