WWII Workout Week: Log Exercises

Editor’s note: This week we’re publishing excerpts from FM 21-20, an Army field manual from 1946 that includes the physical training program used by GIs during WWII. You can read the story behind FM 21-20 here. This series may offer you practical suggestions on exercises to incorporate into your own workouts, or simply inspire you to get in shape and embody the kind of strength and fitness that would make your grandpa proud!

For today’s workout, you’ll need a few friends, a pair of gloves, and a big ol’ log. It’s kind of amazing to see the numerous, wide-ranging exercises that are possible with a tree trunk as your only equipment.

Log Exercises

GENERAL. Log exercises are excellent activities for developing strength and muscular endurance because they require the muscles to contract under maximum loads. The set of log exercises in this section may be used in lieu of the basic conditioning exercises. Using them two or three times a week in 15 to 20 minute periods, provides a welcome change in the physical training program. However, log exercises should not be introduced until the men have become well-conditioned.

SPECIFICATIONS OF LOGS. The logs should be from 6 to 8 inches in diameter. They may vary in length from 14 feet (for 6 men) to 18 feet (for 8 men). They should be skinned, smoothed, and dried. The 14 foot logs should weigh approximately 300 pounds; and the 18 foot ones, 400 pounds. Rings should be painted on the log to indicate each man’s position.

STARTING POSITIONS AND COMMANDS. The men fall in, facing the log and about 4 inches from it. All men assigned to the same log should be approximately the same height. The basic starting positions and commands are as follows:

Army physical training log Right Hand starting position.

a. 1. Starting Position. 2. MOVE. At the command MOVE, move the left foot smartly 12 inches to the left and lower the body into a flat-foot squat. Keep the back flat, head up, and arms between the legs. Encircle the far side of the log with the left hand. Keep the right hand underneath the log. This position is standard unless ordered otherwise.

Army physical training Left Hand standing position.

b. 1. Left Hand Starting Position. 2. MOVE. This command is executed in the same manner as a above except that the left hand is underneath the log and the right hand encircles the far side of the log.

Army physical training Right shoulder position 2.

c. 1. Right Shoulder Position. 2. MOVE. At the command pull the log upward in one continuous motion to the right shoulder. At the same time move the left foot to the rear and stand up facing left. Balance the log on the right shoulder with both hands.

d. 1. Left Shoulder Position. 2. MOVE. This command should be given from the Left Hand Starting Position. At the command MOVE, pull the log upward in one continuous motion to the left shoulder. At the same time move the right foot to the rear and stand up facing right. Balance the log on the left shoulder with both hands.

Army physical training waist position 2.

e. 1. Waist Position. 2. MOVE. From the standard starting position pull the log waist high. Keep the arms straight and fingers laced underneath the log. The body is inclined slightly to the rear, and the chest is lifted and arched.

Army physical training Chest position 2.

f. 1. Chest Position. 2. MOVE. This command should be given after the waist position has been assumed. At the command MOVE, shift the log to a position high on the chest, bring the left arm under the log and hold it in the bend of the arms. Keep the upper arms parallel to the ground.

g. To move the log from the right shoulder to the left shoulder the command is: 1. Left Shoulder Position. 2. MOVE. Upon this command push the log overhead and lower it to the opposite shoulder.

Army physical training Supine position.

h. 1. Supine Position. 2. MOVE. This command is given after the waist position has been assumed. Upon this command cross the legs and sit upon the ground. Assume the supine position with the log resting upon chest and hands. Feet are apart.

i. 1. Starting Position. 2. MOVE. This command is given to return the log to the ground from any of the above positions. Upon this command slowly lower the log to the ground. The hands and fingers must be kept from under the log.

The men holding the logs, in each case, are grouped at the two ends of the log, not distributed over its length. The logs are held in four different positions.

The other men run and jump over all of the logs. This can be varied by jumping over the first log and crawling under the second, and so on.
