Key Highlights:

• Embedding sports medicine teams within Army units under the Holistic Health and Fitness (H2F) model produced measurable performance gains: nearly +18 lb on the deadlift and a 31-second improvement on the two-mile run compared to units without those teams.
• H2F replaces one-size-fits-all morning PT with tailored programs built by strength coaches, physical therapists, and dietitians; early injury evaluation and on-site care reduces lost duty time and bolsters readiness.
• The Army has standardized a new fitness test (Army Fitness Test, official June 1, 2025) and plans further combat-specific assessments; other services are adopting similar human performance programs, signaling a force-wide shift.

Introduction

The stereotype of Army physical training—pre-dawn calisthenics, endless formation runs and uniform drills—still appears in popular portrayals. Real-world preparation, however, has taken a different path. A string of policy changes, program launches and peer-reviewed studies shows the service is deliberately reshaping how Soldiers build strength, endurance and resilience. The Holistic Health and Fitness (H2F) model embeds subject-matter experts directly into units and replaces generic group drills with individualized, mission-focused programs. Results are concrete: Soldiers with embedded sports medicine teams gained strength, cut run times and sustained fewer interruptions to duty because injuries were identified and treated early.

A 2026 study published in the Translational Journal of the American College of Sports Medicine compared Soldiers who trained with unit-based sports medicine teams against Soldiers who did not. The findings are striking and point to a larger cultural and operational transformation across the Department of Defense. This article synthesizes those findings, traces the historical and scientific rationale, examines the organizational implications, and outlines what commanders and decision-makers must do to institutionalize gains across the entire force.

From APFT to AFT: How Army fitness testing shifted to match combat demands

The Army’s fitness assessment evolved dramatically between 2019 and 2026, reflecting a deliberate effort to align testing with combat tasks and contemporary physiology. The old Army Physical Fitness Test (APFT) focused on three events: push-ups, sit-ups and a timed run. The Army Combat Fitness Test (ACFT), introduced to better simulate combat requirements, expanded to six events. By June 1, 2025, the Army adopted the five-event Army Fitness Test (AFT) as the official test of record.

Key changes in the evolution:

• Age and gender-normed scoring to better reflect individual differences and occupational demands.
• Replacement of the leg tuck with the plank, a transition toward measures that assess sustained core stability rather than a single maximal effort.
• Removal of the standing power throw and greater emphasis on functional movements that translate directly to battlefield tasks.
• Announcement of a Combat Field Test (CFT) projected for 2028, intended as a mission-specific physical assessment for Soldiers in combat-related roles.

These changes are not cosmetic. They reflect a clear move to measure and develop attributes—strength endurance, power, load carriage capability and task-specific anaerobic capacity—that matter in combat, and to do so in a way that mitigates injury risk and improves long-term operational readiness.

Roots of embedded performance: how the Army arrived at H2F

The presence of medical and rehabilitation professionals within combat and operational units is not new. The concept stretches back to World War I “reconstruction aides,” who provided early rehabilitative care. More recently, the Army placed physical therapists with Ranger battalions in 2000 and developed programs like Tactical Human Optimization Rapid Rehabilitation and Reconditioning (Thor3) in Special Forces. H2F synthesizes lessons from those efforts and borrows from elite competitive sports and collegiate athletics.

H2F operates on five health-related domains: physical, mental, nutrition, sleep and spiritual. That structure acknowledges the clear interactions between training load, recovery, sleep quality, psychological resilience and nutrition. It treats the Soldier as an integrated human system rather than a collection of discrete fitness metrics. Staffed with strength and conditioning coaches, physical therapists, athletic trainers and dietitians, H2F Performance Teams are meant to be part of the unit’s daily fabric—observing tasks, tailoring workouts and intervening early when injuries or overtraining signs appear.

The 2026 study: causal evidence that embedded experts boost performance

The study “Influence of Sports Medicine Teams on Physical Fitness in U.S. Army Soldiers” compared Soldiers exposed to H2F sports medicine teams against Soldiers without access to those teams over approximately one year. The research design leveraged field testing under real-world operational conditions rather than laboratory control, providing an applied perspective on outcomes relevant to commanders.

Principal findings:

• Strength increased: Soldiers with embedded teams added nearly 18 pounds to their deadlift on average compared to counterparts without teams.
• Aerobic performance improved notably: a 31-second faster two-mile run time for Soldiers with sports medicine teams, despite similar weekly running mileage between groups.
• Training content changed: units with teams shifted from traditional calisthenics and steady-state running toward a broader program that included resistance training, high-intensity interval training (HIIT), cross-training, interval work and plyometrics.

The two-mile run improvement is especially instructive. With weekly mileage comparable across groups, the difference derived from training quality rather than training volume. Program design—targeted intervals, strength-endurance integration and strategic recovery—created physiological adaptations more relevant to aerobic performance and operational tasks than simply adding miles.

Lead author Tyson Grier described the results plainly: Soldiers with sports medicine teams "showed greater physical performance improvements compared to Soldiers without sports medicine teams." The implication for commanders is direct. Embedding subject-matter experts produces performance gains that generic PT cannot.

How specialists produce better outcomes: the training science behind H2F

The performance improvements observed under H2F flow from established, evidence-based training principles. Several mechanisms explain why embedding experts yields measurable change:

• Specificity and transfer: Specialists design workouts that mirror the energy systems, movement patterns and strength demands Soldiers will encounter. Instead of a generic run, programs use interval training and tempo runs that stimulate race-pace economy and improve lactate threshold, directly shaving time off two-mile performances.
• Strength as a foundation: Resistance training increases force production and muscular endurance. Improved deadlift numbers reflect greater posterior-chain strength, which translates into better load carriage and reduced relative effort for demanding tasks.
• Periodization and progression: Subject-matter experts apply planned, progressive overload with cycles of intensity and volume that reduce injury risk while maximizing adaptation. This contrasts with undifferentiated, repetitive PT that can plateau or produce overuse injuries.
• Cross-training and neuromuscular variability: Incorporating plyometrics, mobility work and cross-training develops neuromuscular control and power, improving movement economy and resilience under load.
• Recovery management: H2F teams monitor recovery indicators—sleep, soreness, subjective readiness—and adjust training accordingly. Managing recovery prevents chronic fatigue and supports sustainable performance gains.
• Nutrition and sleep optimization: Dietitians in H2F tailor fueling strategies for training and recovery, while sleep technicians or guidance can improve sleep hygiene—both critical for adaptation.
• Early identification and on-site management of musculoskeletal issues: Physical therapists and athletic trainers evaluate complaints immediately, prescribe conservative management and adjust training to prevent escalation.

These elements combine into a system that trains smarter, not merely harder. The outcome is measured not by more push-ups, but by tangible mission-relevant capacity: increased strength, faster sustained running and fewer duty-limiting injuries.

Injury prevention: early care, efficiency and readiness

Musculoskeletal injuries remain a leading cause of medical visits and limited duty in militaries worldwide. The Stryker brigade study, published in Military Medicine in February 2026, documented the power of embedded care: physical therapists and athletic trainers evaluated 63% of musculoskeletal injuries within one week of onset and managed 59% of them without time lost from duty.

Early evaluation matters. Most musculoskeletal complaints worsen when ignored or when training continues without modification. Timely assessment allows conservative interventions—load management, targeted exercises, manual therapy—that arrest progression and maintain Soldiers on duty. The embedded model enables immediate observation of how Soldiers perform occupational tasks, allowing clinicians to tailor interventions to actual job demands instead of hypothetical deficits.

Two operational gains arise from early intervention:

• Reduced attrition and lost work days: preventing minor injuries from becoming chronic preserves force capacity and reduces the administrative burden of rehabilitation and reclassification.
• Safer training environments: clinicians can identify systemic issues in unit PT or occupational tasks that predispose Soldiers to injury and recommend programmatic modifications.

For commanders, these translate into preserved readiness, fewer replacements, and measurable savings in both time and medical cost. The return on that investment appears in performance metrics and force availability.

Leadership and culture: turning availability into utilization

Embedded teams cannot produce results in a vacuum. Command climate determines whether teams are used and whether Soldiers trust their guidance. Michelle Chervak, injury prevention division chief at DHA-PH, emphasized leadership’s role: commanders should promote team services, discuss outcomes and encourage 100% utilization.

Key leadership practices that convert capability into impact:

• Visibility and endorsement: commanders publicly support SMTs, integrate them into training planning and allocate time for Soldiers to consult team members.
• Policy alignment: scheduling and duty allocations should permit individualized training sessions without penalizing Soldiers for deviating from formation PT when clinically indicated.
• Education and communication: SMTs brief units on their services, expected outcomes and success stories; transparency builds trust and reduces stigma about seeking help.
• Data-driven accountability: commanders track utilization metrics and performance outcomes, reinforcing the link between team engagement and readiness.

Units that treat H2F as a tactical asset—rather than an optional extra—see consistent engagement and better outcomes. The program’s efficacy depends on leaders who view human performance as a strategic responsibility.

Scaling the model: institutional expansion and joint adoption

Operational success in early adopters prompted institutional expansion. On Dec. 8, 2025, the Army announced plans to roll out H2F Performance Teams to every unit. The benefits were clear: increased lethality, reduced injuries and better occupation-specific performance.

Other services followed suit. The Air Force launched a Culture of Fitness initiative, the Navy retooled its Human Performance Optimization effort and the Space Force pursued a Holistic Health Approach with continuous fitness assessments and wearables. These parallel moves indicate shared recognition across services that modern human performance requires specialized personnel, data-driven monitoring and continuous learning.

Scaling challenges include:

• Personnel and training: recruiting, credentialing and deploying enough strength coaches, physical therapists and dietitians to staff units at scale.
• Funding and sustainment: budget allocations must cover salaries, equipment, facility upgrades and continuing education.
• Standardization vs. unit specificity: balancing consistent program standards with flexibility for mission-unique demands.
• Data integration: establishing systems for collecting, safeguarding and analyzing performance and health data across a distributed force.

Technology will help. Wearables, cloud-based performance tracking, and telehealth can extend specialist reach. Yet technology complements rather than replaces in-person expertise; the advantage of embedded teams is their on-the-job observation and timely intervention.

Measuring return on investment: readiness, cost avoidance and mission effectiveness

Military decision-makers require evidence that investments yield organizational returns. The H2F program’s ROI can be framed in three components:

1. Readiness gains: improved fitness metrics translate into higher mission capability. Units with fitter Soldiers can perform physically demanding tasks with less fatigue and fewer performance decrements in austere conditions.
2. Cost avoidance: early injury management reduces medical treatment costs, shorter rehabilitations, fewer medical separations and lower long-term disability expenditures. Less time lost to injury also reduces replacement and retraining costs.
3. Operational effectiveness: fitter Soldiers sustain higher cognitive and physical performance under stress, contributing to mission success. Improved resilience and reduced attrition maintain institutional knowledge and unit cohesion.

A peer-reviewed analysis titled “Evaluating the Return on Investment of U.S. Army H2F Performance Teams” models these benefits and supports continued investment. Commanders do not need perfect actuarial tables to appreciate practical outcomes: fewer injured Soldiers, higher pass rates on fitness tests, and smoother operational deployment cycles.

Practical programming: what changes for unit PT under H2F?

H2F does not abolish unit physical training; it transforms it. Training sessions become more purposeful, accommodate varying ability levels and integrate recovery and injury prevention strategies. Below is an illustrative weekly template showing the balance of modalities favored by sports medicine teams—it is an example, not prescriptive guidance:

• Monday: Strength focus — compound lifts (deadlift/hinge pattern, squat variations), core stability work; mobility circuit; post-session recovery strategies.
• Tuesday: Aerobic intervals — tempo run or interval repeats aimed at improving threshold; complementary lower-body plyometrics.
• Wednesday: Active recovery — mobility, corrective exercises, sleep and nutrition check-ins; individual consults with SMTs.
• Thursday: Power and anaerobic capacity — hill sprints, sled work or loaded carries, circuit incorporating upper-body strength.
• Friday: Tactical simulation — movement under load with task-specific drills and transition conditioning.
• Saturday: Cross-training — cycling, swimming or functional circuits to maintain aerobic stimulus while reducing impact.
• Sunday: Rest and monitoring — objective recovery assessment, nutrition planning, sleep optimization.

Individualization is central. Soldiers with prior injuries follow modified plans; those preparing for advanced fitness standards receive tailored progressions. SMTs monitor objective markers—heart-rate variability, subjective wellness scores, sleep duration—and adjust plans accordingly.

Operational examples and case studies

Several real-world examples illustrate H2F’s impact:

• Special Operations lineage: The Thor3 program in Special Forces demonstrated the value of embedded rehabilitation and conditioning specialists in improving operational longevity and reducing injury timelines. H2F expanded these lessons to the broader force.
• Ranger battalion practice: Embedding physical therapists with Ranger units since 2000 created a culture where maintenance of readiness and rapid injury management became normative.
• Stryker brigade results: The 2026 Military Medicine study of a Stryker brigade found rapid evaluation and management of injuries, with most handled without lost duty time. Operational commanders reported higher unit availability and fewer medical downgrades during deployment cycles.
• Inter-service initiatives: The Air Force’s Culture of Fitness and Navy’s Human Performance Optimization programs provide comparative models. Each service adapts the principle—specialist integration, data tracking and leadership engagement—to its unique tasks and force structure.

These cases demonstrate that H2F is not an experimental pilot but an operationally scalable model with broad applicability.

Barriers and pitfalls: what stops H2F from reaching full potential?

Despite evidence of effectiveness, several obstacles can blunt implementation:

• Cultural resistance: Units steeped in tradition may resist abandoning familiar PT models. Overcoming this requires consistent leadership messaging and demonstration of results.
• Underutilization: Making teams available does not guarantee use. Without command pressure and scheduling flexibility, Soldiers will revert to standard practices.
• Resource mismatch: Rolling out teams across a large force demands sustainable funding and personnel. Shortcuts—such as insufficiently trained staff or inadequate facilities—will undermine outcomes.
• Data privacy and interoperability: Collecting biometric and performance data raises privacy, security and integration concerns. Clear policies and robust IT infrastructure are essential.
• Measurement lag: Some benefits, such as reduced long-term disability or lower medical separation rates, manifest over years. Short-term metrics must be tied to long-term outcomes to justify continued investment.

Addressing these barriers requires coordinated policy, persistent leadership support and transparent performance tracking.

The role of technology: wearables, continuous assessment and telehealth

Wearable devices, continuous fitness assessments and telehealth consultations extend the reach of embedded teams. The Space Force has piloted continuous assessment models that rely on wearable data to monitor readiness. Potential gains include:

• Continuous monitoring of training load and recovery markers (e.g., heart-rate variability), enabling early detection of overtraining.
• Remote consultations that triage cases and deliver follow-up care without removing Soldiers from duty cycles.
• Data aggregation for force-level analytics, informing resource allocation and program adjustments.

Technical solutions are powerful but require governance. Data security, standardized metrics and interoperability with electronic health records must be addressed before scaling.

What commanders should do now: actionable steps to accelerate adoption

Commanders play a decisive role in translating program availability into operational gains. Practical actions include:

• Prioritize formal integration: Add SMT members into pre-deployment planning, unit training cycles and occupational task assessments.
• Budget for access: Ensure time, facilities and equipment are allocated for individualized sessions without penalizing Soldiers.
• Demand reporting: Require periodic briefings from SMTs that present utilization metrics, injury trends and performance outcomes.
• Foster education: Host unit-level workshops where SMTs explain training rationale, nutrition strategies and recovery protocols.
• Reward engagement: Recognize units and individuals who leverage H2F services to improve readiness, creating positive incentives.

Commanders who take these steps accelerate cultural adoption and realize the operational benefits of specialized human performance teams.

Policy implications and the future of military fitness

The Army’s shift toward H2F and the broader inter-service move to performance optimization reflect a paradigm change: human performance is a warfighting capability. Policy implications are extensive:

• Fitness assessment reforms will continue to emphasize occupational relevance, including the planned Combat Field Test for combat-related roles.
• Personnel management may shift to incentivize sustained fitness rather than episodic testing; continuous assessment models could alter promotion and assignment criteria.
• Medical training pipelines will need to expand to supply enough qualified clinicians and strength coaches for an integrated model.
• Procurement priorities will include facilities for performance training, wearable systems for monitoring and data systems for analytics.

These changes require sustained leadership at the service and DoD levels to ensure cohesion, funding continuity and consistent standards across the joint force.

Research gaps and next steps for evidence generation

The 2026 study presents clear early evidence, but further research will refine best practices. Relevant research priorities include:

• Longitudinal studies tracking lifetime outcomes—medical separations, long-term disability and overall career performance—linked to early H2F engagement.
• Comparative studies that isolate which components (strength coaches, PTs, dietitians) drive the largest gains.
• Cost-effectiveness analyses that convert readiness metrics into fiscal terms for budgetary decision-making.
• Implementation science studies that examine how unit culture, leadership style and organizational structure affect utilization and outcomes.

Robust evidence will help calibrate investments and standardize the most effective program features across diverse military occupations.

Real-world analogies: what H2F borrows from elite sports and industry

H2F’s model resembles the staffing of collegiate and professional sports where multidisciplinary support teams surround athletes. Strength and conditioning coaches, athletic trainers, nutritionists, sports psychologists and sleep specialists collaborate to maintain health and maximize performance. Corporations with physically demanding workforces—fire departments, law enforcement agencies and elite tactical teams—also integrate similar approaches, offering lesson-rich case studies.

What distinguishes military application is the scale and range of tasks. Unlike a single sport that prioritizes specific movement patterns, Soldiers face diverse physical demands in varied environments. H2F therefore blends sport-derived programming with occupational specificity and the logistics of large-scale personnel management.

Final observations

A clear trend is visible: the military values human performance as an operational asset and is investing in the personnel and programs required to sustain it. The 2026 study provides empirical support for what advocates have argued for years—specialized, embedded sports medicine teams produce better fitness outcomes and preserve readiness. Converting promising pilots into enduring institutional capability demands leadership, resources and data to guide continuous improvement. Units that embrace the H2F model find Soldiers are stronger, faster and less likely to be sidelined by preventable injuries. That combination—heightened capability with preserved force strength—changes the calculus of readiness and pays dividends across the operational spectrum.

FAQ

Q: What exactly is H2F? A: Holistic Health and Fitness (H2F) is a program that embeds sports medicine and human performance specialists—strength and conditioning coaches, physical therapists, athletic trainers and dietitians—into Army units. It addresses five domains: physical, mental, nutrition, sleep and spiritual health, and provides individualized training, recovery and injury-prevention services aligned with unit missions.

Q: How did the Army fitness test change and why does it matter? A: From 2019 to 2026, the Army shifted from the APFT to the ACFT and then to the five-event Army Fitness Test (AFT) as the official assessment. These changes introduced age/gender-normed scoring, replaced the leg tuck with the plank, removed the standing power throw, and emphasized combat-relevant functional movements. Tests now assess capacities directly linked to battlefield tasks and inform training programs designed to improve mission performance with lower injury risk.

Q: What were the main results of the 2026 sports medicine teams study? A: Soldiers training with embedded sports medicine teams increased deadlift strength by nearly 18 pounds on average and ran the two-mile 31 seconds faster than Soldiers without access to those teams. Training content shifted from traditional calisthenics and steady running to a mix that included resistance training, HIIT, cross-training, interval training and plyometrics.

Q: Why did run times improve if weekly mileage was the same? A: The improvement stemmed from program quality rather than volume. Interval training, tempo runs, strength integration and focused recovery yielded better aerobic economy and lactate-threshold improvements, allowing Soldiers to run faster without increasing mileage.

Q: Do embedded teams reduce injuries? A: Evidence indicates early evaluation and management can prevent escalation of musculoskeletal problems. In one study of a Stryker brigade, embedded clinicians evaluated 63% of injuries within a week and managed 59% without loss of duty time. Early treatment and program modification reduce the likelihood of chronic problems and medical separations.

Q: Will H2F replace traditional morning PT? A: H2F transforms rather than eliminates unit PT. It shifts PT from one-size-fits-all sessions to individualized, mission-aligned programs designed by specialists. Unit PT remains an operational tool but is supplemented and often redesigned to reflect evidence-based practices.

Q: How do commanders ensure the program is used effectively? A: Leadership must visibly endorse and integrate SMTs into training plans, allocate time and resources for utilization, require reporting on outcomes, promote education and reward engagement. Cultural acceptance depends on consistent command messaging and practical support.

Q: How will the Combat Field Test (CFT) affect Soldiers? A: The CFT, projected for 2028 for combat-related roles, aims to assess physical capacities directly relevant to combat tasks and further align training with occupational demands. It will require units to prepare Soldiers for task-specific performance and is likely to increase the value of H2F resources in those career fields.

Q: What are the main obstacles to full implementation? A: Scaling H2F requires staffing capacity, sustained funding, data governance for wearable and health data, and cultural change within units. Under-resourced or token deployments of SMTs will limit program effectiveness.

Q: Is there evidence of financial return on investment? A: Peer-reviewed analyses and operational studies suggest ROI via reduced medical costs, fewer lost-duty days and improved readiness. Quantifying ROI precisely depends on unit type, injury baselines and deployment tempo, but data supports the economic rationale alongside operational benefits.

Q: How does H2F compare to civilian athletic programs? A: H2F borrows the multidisciplinary support structure of collegiate and professional sports but adapts it to a broader set of tasks and environmental stresses. Military application emphasizes occupational specificity, large-scale deployment and integration with medical and personnel systems.

Q: Where can Soldiers and commanders find H2F resources? A: The official H2F portal and service-specific human performance pages provide training materials, program descriptions and contact information for local H2F Performance Teams. Command channels and unit medical staff can also coordinate direct access to team services.

Q: What should a Soldier do if they are skeptical of H2F? A: Soldiers are encouraged to consult with SMT members individually. Confidential, evidence-based assessments and small-group education help overcome skepticism. Early performance improvements and pain mitigation often convert doubters into advocates.

Q: What research remains to be done? A: Longer-term, longitudinal studies tracking career outcomes, detailed component analyses to identify which specialist roles drive the largest effects, and cost-benefit assessments that convert readiness gains into fiscal terms are priority research needs.

Q: Can technology replace SMTs? A: Technology—wearables, telehealth and analytics—extends specialists’ reach and improves monitoring, but does not replace the on-site observation, manual assessment and nuanced programming that embedded clinicians provide. Technology supplements expertise rather than substitutes for it.

Q: How do these changes affect deployment training and pre-deployment readiness? A: Units that incorporate H2F see improved pre-deployment readiness because Soldiers arrive physically prepared and with fewer chronic complaints. Training shifts to target mission-specific tasks and emphasizes recovery and readiness monitoring, reducing last-minute remediation and medical issues during deployments.

Q: If my unit doesn’t yet have an SMT, what steps can be taken now? A: Begin by adopting the principles: integrate strength training into weekly cycles, include interval and cross-training modalities, prioritize recovery and sleep, and establish rapid referral pathways to medical staff for early injury assessment. Commanders should document outcomes and advocate for formal SMT allocation.

Q: How quickly do Soldiers typically see benefits from H2F programs? A: Performance improvements can appear within months when training is appropriately structured and recovery is optimized. Strength gains and running economy improvements often manifest within a 12-week cycle, with broader readiness and reduced injury incidence solidifying over the course of a year of consistent application.
