ndition, the dumbbell instructor turns his attention to
exercising the great muscles of the body, beginning with those of the
back, strengthening which holds the body erect, thus increasing the
chest capacity, invigorating the digestive organs, and, in fact, all the
vital functions. By the use of very light weights an equal and
symmetrical development of all parts of the body is obtained, and then
there are no sudden demands on the heart and lungs.

After the dumbbell comes exercise with the round, or bar bell. This is
like the dumbbell, with the exception that the bar connecting the balls
is four or five feet, instead of a few inches in length. Bar bells weigh
from one to two pounds each and are found most useful in building up the
respiratory and digestive systems, their especial province being the
strengthening of the erector muscles and increasing the flexibility of
the chest.

Of all fixed apparatus in use the pulley weight stands easily first in
importance. These weights are available for a greater variety of objects
than any other gymnastic appliance, and can be used either for general
exercise or for strengthening such muscles as most require it. With them
a greater localization is possible than with the dumbbell, and for this
reason they are recommended as a kind of supplement to the latter. As
chest developers and correctors of round shoulders they are most
effective. As the name implies, they are simply weights attached to
ropes, which pass over pulleys, and are provided with handles. The
common pulley is placed at about the height of the shoulder of an
average man, but recently those which can be adjusted to any desired
height have been very generally introduced.

When more special localization is desired than can be obtained by means
of the ordinary apparatus, what is known as the double-action chest
weight is used. This differs from the ordinary kind in being provided
with several pulleys, so that the strain may come at different angles.
Double-action weights may be divided into three classes--high, low, and
side pulleys--each with its particular use.

The highest of all, known as the giant pulleys, are made especially for
developing the muscles of the back and chest, and by stretching or
elongating movements to increase the interior capacity of the chest. If
the front of the chest is full and the back or side chest deficient, the
pupil is set to work on the giant pulley. To build up the side-walls he
