Keep the elbows back so that the entire thorax is lifted forward and up; at the same time take a deep inhalation.] At "Two" the arms begin to fall and the body bends forward from the waist, head up and eyes front, until, at "Four," the body has reached the limit of motion and the arms have passed the sides and have been forced back and up (as the trunk assumes a horizontal position) as far as possible.

At this point the abdomen should be well drawn in at the finish of exhalation.
(Note that in this figure the feet are together, an incorrect position for this exercise.) For a third time, on a count of "One, two, three, four" the body is straightened, reaching an upright position, with arms straight forward at "Three." "Cross" is assumed at "Four." As the body is straightened from the "Wing" position, a full breath should be taken, the lungs being filled, slowly, to the maximum as "Curl" is finally reached.

This breath should be retained and then exhaled as the "Wing" position is taken.

Inhale through the nose.
[Illustration: CRAWL.

AT THIS POINT THE RAISED ARM SHOULD BE CURVED OVER THE HEAD] The entire movement should be repeated five times.
In the "Curl" position the head and shoulders should be thrown well back and the fists should go well up into the armpits.
