Increasing in height as the first preliminary to yoga physical education those who find that they are below the average height should try to increase the same.In considering the possibility of making one body taller the first important fact is that the height depends upon the skeleton i.e the growth and condition of the bones.There are really three divisions which determine the complete stature of an individual viz.
(i) the length of the legs and
(ii) the spine and
(iii) the height of the cranium.
Usually great variations in height are chiefly due to the differences in the length of the legs and the spine since the height of the cranium is more or less uniform.
Two since the extremities are largely responsible for the increase in height the need of such constitutional exercise as would allow maximum stretching of the extremities deserves special emphasis and attention because any attempt to improve the stature by other special methods must fail so long as these fundamental requirements are neglected.Any stretching of the body at full length therefore is of utmost importance for three distinct purposes.
(i) relieving the compression of the cartilages of the spine
(ii) stretching of the skeletal muscles more particularly of the extremities and
(iii) encouraging freedom to and growth of the lungs, heart, and other vital organs.
Although the vital organs function automatically and involuntarily it is an accepted fact that through the immediate control of the skeletal muscles one can increase the activity of the inner vital organs indirectly by making demands upon the large muscles which are developmentally related to them.
