Sit erect, as tall as possible. Expand the chest fully, carry the
arms forward, then backward, gripping the hands almost under the
shoulders, chest out as far as possible, taking a deep breath.
Repeat this rhythmically many times, sustaining as far as possible
the expansion of the chest.
It will be observed that there will come naturally a desire to sit up.
It may be well before sitting up to turn on the back and rest a moment
and feel the enjoyment of the actions that have been in the body. If the
exercises have been properly practiced, there will be a sense of ease
and satisfaction.
