In an effort to bolster combat readiness among its ranks, the U.S. Marine Corps is set to implement notable changes to its physical fitness and body composition standards beginning January 1, 2026. These updates are designed to ensure that all Marines are physically equipped to meet the demands of combat roles.
Guidance from the Secretary of War
A memorandum issued by the Secretary of War on September 30, 2025, has laid out new fitness criteria to improve combat efficiency across the military. The directive calls for gender-neutral standards for combat positions and tougher overall fitness requirements. The Marine Corps will enact these changes as detailed in MARADMIN 613/25, published on December 18, 2025.
The updates focus on ensuring Marines are prepared for the sustained physical performance needed in direct combat operations.
Revised Physical Fitness Testing
The updated Physical Fitness Test (PFT) will apply sex-neutral scoring for Marines in combat arms roles. This involves a unified scoring system for male and female Marines based on the male, age-appropriate standards outlined in Marine Corps Order 6100.13A.
Marines in combat arms must score at least 210 points out of 300, equating to 70% of the maximum score. Meanwhile, non-combat arms Marines will continue to follow existing sex- and age-adjusted standards.
The PFT will remain an annual requirement, conducted between January 1 and June 30. Interim measures will guide units during the transition, with full integration expected within a year.
Updating Body Composition Standards
The Marine Corps is also set to revise its height and weight standards by adopting a waist-to-height ratio (WHtR) approach. This shift aims to provide a more precise assessment of body composition, aligned with the Secretary of War’s directives.
Until the new system is fully implemented, the current height/weight and tape test methods will be used, supplemented by bioelectrical impedance analysis when necessary. Detailed service-specific standards will be forthcoming.
Understanding the Waist-to-Height Ratio
The waist-to-height ratio is determined by dividing waist circumference by height, both measured in inches. A ratio under 0.55 generally suggests a lower risk, whereas a ratio of 0.55 or more may indicate increased risk, echoing standards from other branches like the Air Force.
- Ratio < 0.5: Optimal
- Ratio 0.5–0.54: Low to moderate risk
- Ratio ≥ 0.55: Higher risk (potential for further evaluation)
Marines should refer to official resources for precise implementation details as they are issued.
Readiness and Adaptability
These adjustments reflect the Marine Corps’ dedication to maintaining high physical standards. The focus on fitness is crucial for Marines tasked with defending the nation. The changes, particularly for those in combat roles, underscore the importance of excellence in warfighting capabilities.

The updates aim to ensure the force remains versatile and prepared for operational needs. Units are encouraged to tailor their training to accommodate these transitions smoothly.
