  individualize—the training program to improve absolute workload to avoid injury. Commanders who
  understand and apply the concepts of absolute workload and relative workload can better direct their H2F
  personnel and align resources to meet their units’ missions.
  Table 6-1. Structural requirements
  Structural Requirement Description
  Agility The ability to bend, rotate and twist in the frontal, transverse and sagittal
  planes and use that ability to change direction.
  Coordination The accuracy and speed of limb and trunk movement.
  Dynamic balance The ability to move under control at speed and with varying load.
  Kinesthesia The perception of the body’s position in space during movement.
  Pace The ability to set the correct speed of an activity to manage fatigue.
  Load tolerance The ability of the skeletal system to bear weight.
  Flexibility The range of motion across single or multiple joints that allows the body to be
  positioned for optimal movement.
  Static balance The ability to maintain a stable position over a base of support.
  Body composition The percentage of lean muscle and other body tissues.
  Bone density The thickness and quality of the bone that provides its strength.
  Perception The understanding of correct technique and effort that builds skill.
  Frontal plane Divides the body front and back.
  Transverse plane Divides the top and bottom.
  Sagittal plane Divides the body left and right.
  PHYSICAL COMPONENTS
  6-6. Physical readiness includes the following components:
  * Muscular strength.
  * Hypertrophy.
  * Muscular endurance.
  * Aerobic endurance.
  * Anaerobic endurance.
  * Power.
  6-7. Muscular strength is the amount of force a muscle or a group of muscles can generate. Examples
  include a Flexed Arm Hang for fifteen seconds, one repetition of a Bench Press at maximum weight, or
  extracting a casualty from a turret. The gold standard for measuring muscular strength is the one repetition
  maximum. It is the heaviest weight a Soldier can lift and is best calculated with weight training exercises
  such as the Bench Press, Squat, or Deadlift. High levels of strength that support the mission can certainly be
  achieved without lifting this amount of weight. In fact, leaders need to use the one repetition maximum
  approach sparingly. Leaders can use the repetition maximum formula (paragraph 4-25) to calculate one
  repetition maximum without complete a one repetition maximum testing. The heaviest weight a Soldier can
  lift 3 times or 10 times would be a three repetition maximum or ten repetition maximum, respectively.
  6-8. Hypertrophy is increase in muscle size, which can be achieved through a blending of muscular strength
  and muscular endurance training. When Soldiers use moderate to heavy loads (65–85 percent of one
  repetition maximum), a greater number of repetitions and a variety of speeds, they are building muscle mass.
  6-9. Muscular endurance is the ability of a muscle or muscle group to repetitively perform work for an
  extended period. Examples include lifting duffel bags onto truck beds, loading 155-millimeter rounds, or
  performing Climbing Drill 1. Muscular endurance, in combination with aerobic and anaerobic endurance, is
  required to tolerate carrying progressively heavier loads over greater distances on uneven and steeper terrain
  and at faster speeds.
