Which document would you refer to for guidance on holistic health and fitness?

The correct choice is the field manual FM 7-22, which focuses specifically on the Army's approach to physical readiness and holistic health. This document outlines comprehensive strategies for physical fitness, including exercise principles, nutrition, and mental well-being as essential components of a soldier's overall health. Holistic health and fitness emphasize the idea that physical performance is influenced not only by exercise but also by mental resilience, nutrition, and recovery strategies. By referring to FM 7-22, individuals can learn about training methods, conditioning, and ways to integrate fitness into a balanced lifestyle, which is essential for maintaining operational readiness and improving quality of life.

The other documents pertain to different subjects, such as body composition standards (AR 600-9) or training and readiness (UR 350-1), thus not fully addressing the complete picture of holistic health and fitness.
