OBSTACLE COURSES ARE TOUGHENERS

Running is one of the best leg and wind conditioners. In
obstacle-course running men must progress over, under,
around, and through obstacles placed in their way. Usually
obstacle courses are designed to include activities requiring
use of arms as well as legs. Natural obstacles should be
used wherever possible, but many satisfactory courses are
constructed on running tracks, level areas, or even indoors.
It is desirable to keep all physical training activities out-of-
doors as much as possible and obstacle courses lend them-
selves to various phases of the program.

In general, provision is made for the following types of
physical maneuvers in the Navy’s obstacle courses: (1)
Running, including endurance running, sprint running, crouch
running, running with heavy weights, zigzag running, run-
ning over loose terrain, and running interspersed with occa-
sional jumping, hand vaulting, and ducking under impro-
vised booms; (2) falling, including falling with complete
pack, falling to the side, falling and rolling, and falling while
at full speed; (3) jumping, across ditches, from various levels
or heights, and across stationary objects; (4) hurdling, over
obstacles of various heights and widths; (5) crawling,
around objects, through tunnels, and under low barriers;
(6) climbing, up and down wood or rope ladders, up and
down suspended lines, up and down cargo nets, over high

barriers, and up and down sharp inclines, either natural or
constructed; (7) balancing, walking on balance beams, nar-
row inclines, or narrow or confined space; (8) vaulting, over
various objects such as rails and capstans (improvised), low
barriers, or other similar barricades; and (9) squeezing
through small openings.

Hand-over-hand, which helps arm and shoulder strength, is
universally used on obstacle courses. Close-ups of other
obstacles in general use are shown on the next two pages.
