THE MUSCLES AND HOW TO USE THEM 



57 



The evening is not the best time for exercise because the 

 body is tired after the labor of the day. Ordinary work or 

 moderate exercise, as walking, is beneficial at almost any 

 time, except, perhaps, just after a full meal. 



83. Different Kinds of Exercise. The kind of exercise 

 needed depends very much upon one's daily occupation. 

 Persons who sit at desks, 



stand at counters, or 

 work in close rooms, as 

 clerks, teachers, tailors, 

 printers, etc., are prone 

 to diseases often traced 

 to lack of bodily exercise 

 and to foul air. 



All well persons should 

 do some work or take 

 some exercise every day. 

 To get and to keep vigor- 

 ous health it is not at all 

 necessary to increase the 

 size of the muscles very 

 much or to do great feats 

 of strength. 



84. Walking. Walk- 

 ing is perhaps the most 

 convenient and useful of 



all the exercises for most people. It takes us into the 

 open air and bright sunlight. It puts new vigor into the 

 work of many important muscles of the chest, the abdo- 

 men, and the limbs. With a brisk walk every day while 

 in good health, and taking care to keep warm and dry, no 

 one need suffer from lack of proper exercise.
