Two--While the arms are thrown forcibly backward, the fore-arms are as much as possible bent upon the arms, and the palmar sides of the wrists are turned forward and outward (Plate I. fig. 5.) The two motions are to be repeatedly and rather quickly performed. A modification of the same movement is performed as a separate extension motion, but may be given in continuation, with the numbers following these, as words of command. Three--The arms are extended at full length in front, on a level with the shoulder, the palms of the hands in contact. (Plate I. fig. 6.) Four--Thus extended, and the palms retaining their vertical position, the arms are thrown forcibly backward, so that the backs of the hands may approach each other as nearly as possible. These motions, also, are to be repeatedly and rather quickly performed. Another extension motion, similarly added, consists in swinging the right arm in a circle, in which, beginning from the pendent position, the arm is carried upward in front, by the side of the head, and downward behind, the object being in the latter part of this course to throw it as directly backward as possible. The same is then done with the left arm. Lastly, both arms are thus exercised together. These motions are performed quickly. THE INDIAN CLUB EXERCISE. THE PORTION ADOPTED IN THE ARMY. 1st. A club is held by the handle, pendent on each side (Plate II. fig. 1);--that in the right hand is carried over the head and left shoulder, until it hangs perpendicularly on the right side of the spine (Plate II. fig. 2); that in the left hand is carried over the former, in exactly the opposite direction (Plate II. fig. 2), until it hangs on the opposite side; holding both clubs still pendent, the hands are raised somewhat higher than the head (Plate II. fig. 3); with the clubs in the same position, both arms are extended outward and backward (Plate II. fig. 6); they are lastly dropped into the first position. All this is done slowly.
