What does the Toughening phase focus on in physical readiness training?

The Toughening phase of physical readiness training is primarily focused on endurance and strength development. This phase is essential for building a solid foundation of physical readiness that enables Soldiers to perform their duties effectively. During this phase, the training incorporates activities that challenge both muscular strength and cardiovascular endurance, leading to improved overall fitness levels.

The emphasis on endurance and strength is crucial because it prepares Soldiers for the rigors of combat and enhances their ability to meet the physical demands of military operations. As physical readiness is a key component of a Soldier's performance, this phase ensures they can sustain prolonged activities and recover well, thereby improving their operational capability.

While other aspects like acclimatization, skill reinforcement, and injury prevention are important components of a comprehensive training program, they do not define the primary focus of the Toughening phase as specifically as endurance and strength development do.
