The neck should be kept back all the time.] At "Two" the arms are slowly returned to "Cross" as all air is exhaled and the heels are lowered to a normal position.

Care should be taken to see that the arms are not allowed to drop below the level of the shoulders or to rise more than forty-five degrees.

The arms should be raised and lowered ten times.
The caution in the "Grate" position is not to let the arms drop, even a fraction of an inch, below the horizontal, and not to let them go up above the angle of forty-five degrees, for in either of these cases there is a distinct rest given to the shoulder muscles.

Most of the ordinary exercises of this kind carry the arms above the head; this always releases the effort of the shoulder muscle and is therefore nearly valueless as an exercise for these members.
Another fault in this exercise is letting the head come forward.

The neck should be kept back all the time.
