Hyperborean Program by Sieg Grun is a short “training manual” that blends physical fitness guidance with a mythic/spiritual frame. It presents itself as a practical system for cultivating a “warrior/berserker” state—described as a disciplined reserve of aggression, focus, and endurance—by steadily hardening the body while sharpening attention and will.
Most of the book is structured like a regimen: it outlines strength and conditioning work (with emphasis on fundamental movements, progressive effort, and avoiding injury), plus complementary practices meant to increase resilience and composure under stress. The program encourages consistent training habits—calisthenics, weights, and/or martial-arts-style drills—along with warm-ups, sensible volume, and gradual progression rather than reckless intensity.
Alongside workouts, Grun adds lifestyle prescriptions intended to “forge” mindset: sleep and daily rhythm, periods of quiet/solitude, and deliberate mental training such as meditation or contemplation. The book treats these as inseparable—physical capability is presented as the foundation, while mental practices are the “control system” that channels intensity rather than letting it become chaos.
Diet is framed as functional fuel. It recommends simple, minimally processed food choices and basic macronutrient guidance, plus occasional fasting or controlled restriction to build discipline and reduce dependence on comfort. Environmental stressors—especially cold exposure—are presented as tools for conditioning (with practical notes on duration and frequency), reinforcing the larger theme of voluntary hardship as character training.
Overall, the book reads less like a narrative and more like a compact blueprint for self-conditioning: a mix of fitness programming, ascetic habit-building, and symbolic language (Hyperborea, the “warrior path”) used to motivate a strict regimen. The core promise is that persistent, structured practice—training, restraint, and recovery—can produce a tougher body and a more controlled, forceful inner posture.
