These be the exercises which I terme within dores, bycause they may be practised at home vnder couert, when we cannot go abroad for the weather: though all may be vsed abroad, if the roome and the weather do serue abroad. Wherein I take it, that I haue kept _Galenes_[24] rule in chusing these exercises, and that they be all both pleasant, profitable and parable, the perfect circunstances of all good and generall exercises, not to be costly to compasse, nor vnpleasant to loth them, nor vnprofitable to leaue them. Those that require more libertie of roome, to raunge at will, or to forrage in the field, be these, which I noted before, _walking_, _running_, _leaping_, _swimming_, _riding_, _hunting_, _shooting_, and _playing at the ball_.
Among those exercises which be vsed abroade, what one deserueth to be set before walking, in the order and place of traine: what one haue they more neede to know, which minde, the preseruation and continuaunce of health? what one is there, which is more practised of all men, and at all times, then walking is? I dare saye that there is none, whether young or olde, whether man or woman, but accounteth it not onely the most excellent exercise, but almost alone worthy to beare the name of an exercise. When the weather suffereth, how emptie are the townes and streates, how full be the fieldes and meadowes, of all kindes of folke? which by flocking so abroad, protest themselues to be fauourers of that they do, and delite in for their health. If ye consider but the vse of our legges, how necessarie they be for the performaunce of all our doings, _nature_ her selfe seemeth to haue appointed _walking_, as the most naturall traine, that can be, to make them discharge their duetie well. And sure if there be any exercise, which generally can preserue health, which can remedie weaknesse, which can purchace good hauiour, considering it is so generall, and neither excludeth person nor age, certainly that is _walking_. Herevpon Physicians when they entreat of this argument, vse alwaye to giue it, the place of preferment and birthright in this kinde. The auncient Princes, and common weales so highly esteemed of it, as in the places appointed for exercise, whether within their great buildinges, or without, they seemed to minde no one thing more: and still prouided walking roomes, to serue for all seasons and times of the yeare, some couert and close, some vncouert and open, some secret and hidden. The reason why they thus regarded _walking_, was great, for as it seemeth to be, so it is in verie deede wholly consecrate to the vse of health.
