About this book
Elias spent three years as his own guinea pig — gaining 15 kilos of muscle, halving his body fat, running ultra distances on minimal training, and sleeping in laboratories — to answer one question: what is the minimum effective dose for a capable body?
The Hardy Body collects only what survived testing: the two-day-a-week strength protocol, the slow-carb eating template used by thousands of readers, the 15-minute sleep fixes, and the honest numbers behind cold plunges, kettlebells, and perfect posture.
What's inside
- Occam's Protocol: two 30-minute sessions a week that added 10+ kilos of lean mass in the case studies.
- Slow-carb, simplified: five rules, thirty staple meals, one weekly feast day — no calorie maths.
- Sleep engineering: temperature, timing, and the 90-minute rule for shift workers and new parents.
- Fix the pain: the prehab routines for backs, knees, and shoulders that desks destroy.
- Measure honestly: which gadgets earn their drawer space — and which are theatre.
Who it's for
Busy people who want capability, not cosmetics: beginners who've never touched a barbell, lifters stuck for years, and anyone whose back aches by Thursday. Every protocol includes a “no gym” variation and a medical-safety note on when to see a professional first.
