; repeat four times.

TOE EXERCISE

=843. 1. Arms backward, 2. CROSS, 3. RISE ON TOES.=

Two counts; repeat 8 to 10 times, Fig. 14.

[Illustration: Fig. 14]

The body is raised smartly until the toes and ankles are extended as
much as possible; heels closed; head and trunk erect; in recovering
position heels are lowered gently; breathe naturally.

COMBINATION EXERCISE

=844.= This exercise brings into play practically all of the muscles
that have been used in the preceding exercises.

=1. LEANING REST IN FOUR COUNTS.=

Repeat 6 to 8 times, Figs. 15, 16.

[Illustration: Fig. 15]

[Illustration: Fig. 16]

At =one= knees are bent to squatting position, hands on the ground
between knees; at =two= the legs are extended backward to the leaning
rest; at =three= the first position is resumed, and at =four= the
position of attention; hands should be directly under shoulders; back
arched; knees straight; head fixed; execute moderately fast; breathe
naturally.

WALKING AND MARCHING

=845.= The length of the full step in quick time is 30 inches,
measured from heel to heel, and the cadence is at the rate of 120
steps per minute.

Proper posture and carriage have ever been considered very important
in the training of soldiers. In marching, the head and trunk should
remain immobile, but without stiffness; as the left foot is carried
forward the right forearm is swung forward and inward obliquely across
the body until the thumb, knuckles being turned out, reaches a point
about the height of the belt plate. The upper arm does not move beyond
the perpendicular plane while the forearm is swung forward, though the
arm hangs loosely from the shoulder joint. The forearm swing ends
precisely at the moment the left heel strikes the ground; the arm is
then relaxed and allowed to swing down and backward by its own weight
until it reaches a point where the thumb is about the breadth of a
hand to the rear of the buttocks. As the right arm swings back, the
left arm is swung forward with the right leg. The forward motion of
the arm assists the body in marching by throwing the weight forward
and inward upon the opposite foot as it is planted. The head is held
erect; body well stretched from the waist; chest arched; and there
should be no rotary motion of the body about the spine.

As the leg is thrown forward the knee is smartly extended, the heel
striking the ground first.
