EXERCISE. 57 



14. Varieties of Exercise. In walking, the muscles 

 chiefly employed are those of the lower limbs and trunk; 

 the muscles of the arms are hardly used. Rowing and 

 riding are better, since in them nearly all the muscles are 

 exercised. No one exercise employs in equal proportion 

 all the muscles, and gymnasia, in which different feats of 

 agility are practised so as to call different muscles into 

 action as may be desirable, have a deserved popularity. 

 It should be borne in mind, however, that in the arms 

 delicacy of movement is more important to many per-

 usually practised indoors is also a great drawback to 

 their value. Out-of-door exercise in good or even mod- 

 erate weather, is better than any other, and every one can 

 at least take a walk. The daily " constitutional " is, how-

 half its value if unattended with feelings of mental re- 

 .laxation and pleasure. Active games, for this reason,

 Muscle. Few persons can continue to put both body and 

 mind to severe daily work without risk. Many a college 

 student has completely broken down his health in the 

 attempt. Every one should, however, regularly use both 



14. What muscles are left unexercised in walking ? Why are row- 

 ing and riding better exercises ? Why are gymnasia useful ? What 

 is the chief drawback to gymnastics ? Why are active games espe- 

 cially valuable ?

 athletics and study ? What should every cne do?
