Carrying logs close to the elbows reduces the moment arm, which is the distance between the point of force application and the pivot (in this case, the shoulder joint), thereby reducing the torque and the amount of energy required to carry the logs. This method allows for carrying more wood efficiently compared to the options that involve carrying with hands or making multiple trips.
