Army Mandates Waist-to-Height Ratio of 0.55 Under Hegseth Fitness Directive
The new body composition standard creates a measurable, uniform threshold that will determine referral to remedial nutrition programs — shifting Army fitness enforcement toward a continuous metric...
The U.S. Army on Tuesday announced a new physical fitness requirement mandating that all soldiers maintain a waist-to-height ratio of 0.55 or lower, according to reporting by the Washington Examiner citing the Army's policy release. The ratio is calculated by dividing a soldier's waist circumference by their total height. The policy was issued in alignment with a directive from Defense Secretary Pete Hegseth, who has publicly prioritized raising fitness standards across the Department of Defense — referred to in his rebranding effort as the Department of War.
Soldiers who do not meet the 0.55 threshold will be referred to the Army Body Composition Program (ABCP), the service's existing framework for addressing weight and nutrition noncompliance, according to the Washington Examiner report. The ABCP provides nutrition counseling and structured remediation timelines. The Army has not publicly released the full text of the updated regulation as of July 7, 2026; the specific enforcement timeline, appeals process, and consequences for repeated noncompliance remain unconfirmed in available public records.
The waist-to-height ratio is a body composition measurement used in clinical and military contexts as an alternative or supplement to body mass index (BMI). Unlike BMI, which uses only weight and height, the waist-to-height ratio captures central adiposity — fat concentrated around the midsection — which military and public health researchers have linked to cardiovascular risk. The Army has previously used tape-test measurements under AR 600-9, the existing Army Body Composition Program regulation, though it is not yet confirmed whether Tuesday's directive amends or supplements that regulation.
Hegseth has stated publicly, including in testimony and public remarks documented in Congressional and departmental records, that improving the physical readiness of the force is a stated priority of his tenure. The specific policy directive that authorized Tuesday's Army announcement has not been posted to a public federal register entry as of publication time. It is unknown whether parallel waist-to-height ratio standards are being prepared for the Navy, Marine Corps, Air Force, Space Force, or Coast Guard.
What remains unknown includes the full regulatory text of the new Army standard, its effective date, the specific consequences for soldiers who remain noncompliant after completing the ABCP, and whether the standard applies uniformly across all Military Occupational Specialties including those with physically atypical body composition profiles. The Army's official policy update, if published as a revision to AR 600-9 or a standalone directive, would appear in the Army Publishing Directorate database and would provide those details.
