  Throughout a Soldier’s career, optimal programming has the secondary effect of preventing degradation in
  performance and behavior that might negatively impact readiness.
  1-5. H2F doctrine recognizes that Soldier readiness depends on the proper combinations of physical fitness
  (such as strength, speed, and endurance) and foundational health (such as the cardiovascular, respiratory,
  immune, and hormonal systems) that are optimized through careful attention to nutritional readiness, mental
  readiness, spiritual readiness, and sleep readiness. Nutrition—the food, beverages, and supplements in a
  Soldier’s diet—provides the nutrients needed to meet the physical demands of training and combat. Soldiers
  must also maintain mental readiness—the exceptional mental flexibility and endurance, outstanding self-
  initiative and superior judgment required in combat. Spiritual readiness supports individual and collective
  readiness as Soldiers negotiate challenging moral and ethical situations in training or operational
  environments. Finally, proper sleep sustains brain function, cognition (thought processing), the immune
  system, and recovery after physical activity.
  INDIVIDUALIZATION
  1-6. For most of its history, the Army has used an industrial-scale approach to physically train its
  formations. The optimal physical fitness of the individual was constrained by the need to raise the fitness of
  the whole. H2F doctrine shifts the focus to individualized training programs with continuance of training in
  a collective setting. From 2020, the Army will train the whole of each individual Soldier to ensure the
  readiness of the Army. The H2F System supports that approach with expert H2F performance teams,
  equipment, and facilities. It uses the best exercise science and best coaching practices to assess each Soldier
  and customize to his or her needs. Each Soldier, regardless of physical condition, has his or her own program.
  A periodized, purposeful physical training program implemented across the enterprise allows Soldiers to
  move from one duty station to another without interruption in their readiness training progression.
  1-7. Training schedule development for individual Soldiers and units is a complex process. Several
  variables impact the ability to apply one training schedule across all of the Army. These variables include
  how units fill, the length of the training cycle, time until deployment, cadre-to-Soldier ratios, shift work,
  availability of H2F personnel, equipment and facilities, military occupational specialty (MOS)-specific
  training, and environmental (austere, hot, cold, and seasonal) considerations. The H2F System will provide
  the best training approaches to accommodate these variables and implement rational, optimized programs.
  IMMERSION
  1-8. Immersive programming owned by and delivered in the unit builds cohesion, ésprit de corps, and trust.
  Within a standardized system (where unit readiness resources and outcomes are similar across the enterprise),
  different unit needs drive variations in the training program to meet the demands of resource constraints,
  organizational changes, and new mission sets. H2F doctrine links physical and mental training domains, and
  does so in a system staffed and equipped at levels equivalent to those found in elite performance settings.
  The facilities, equipment, personnel, and leader education elements described in this doctrine make the
  performance readiness training experience an immersive one. Immersive training makes the best choice the
  only choice. It provides the most comprehensive pathway to optimize lethality and ensure overmatch in multi-
  domain operations.
  ELEMENTS
  1-9. The H2F System is comprised of five critical elements: governance, program, equipment and facilities,
  personnel and leader education. These elements are essential to the success of Army readiness. They ensure
  and sustain Soldier readiness. See figure 1-1.
  GOVERNANCE
  1-10. The Army’s strategic leaders are responsible for the readiness of the Army and the overall governance
  of the H2F System. Strategic leaders establish the policies and regulations, define objectives, allocate
  resources, and implement quality controls to deliver performance readiness. This is the governance process.
