Physical Exercise 



properly exercised not only increase in size, but are better 

 enabled to get rid of any needless accumulation of fat, 

 as well as useless waste matters, 

 which may exist in the tissues. 



Muscular exercise provides the 

 joints with more powerful liga- 

 ments and better developed bony 

 parts. After long confinement to 

 the bed from disease, the joints 

 have wasted ligaments, thin carti- 

 lages, and the bones are of smaller 

 proportions. 



94, Muscular Coordination and 

 Physical Training. He who has 

 been physically well trained has 

 both a more economical and a 

 more intelligent use of his mus- 

 cles. He has acquired the art of 

 causing his muscles to act in har- 

 mony. Movements once difficult 

 are now carried on with ease. 

 The power of coordination is 

 increased, so that a desired end 

 is attained with the least expendi- 

 ture of physical force and nervous 

 energy. In learning to row, play 

 baseball, ride the bicycle, or in 

 any other exercises, the beginner makes his movements 

 in a stiff and awkward manner. He will use and waste 

 more muscular force in playing one game of ball, or in 

 riding a mile on his wheel, than an expert would in doing 

 many times the work. He has not yet learned to balance 

 one set of muscles against its antagonists. 



FIG. 37. The Standard 

 Special Chest Weight. 



(A convenient machine by means 

 of which all the muscles of the 

 body may be easily and pleas- 

 antly exercised, with sufficient 

 variations in the movements to 

 prevent monotony. A space 

 about 6 ft. wide, 6 ft. deep, and 

 7 ft. high is required in exercis- 

 ing with this machine.)
