Why Our Coaching Works — and Where Young Coaches Should Start
At Hardbody, our training system wasn’t built on trends or guesswork. It was built on decades of education, mentorship, and applied science — shaped by some of the world’s most respected strength coaches, sport scientists, and performance leaders.
Whether you’re a parent who wants to understand why Hardbody works, or an aspiring coach looking to level up your own education, this post is your behind-the-scenes tour of the 12 books that shaped how we coach.
We’ve grouped them into 4 themes:
- Foundational Classics
- Science & Physiology
- Periodization & Program Design
- Applied Strength Coaching
Foundational Classics
Why this matters for parents/athletes: These are the blueprints behind how world-class athletes are built.
Why this matters for coaches: These are your textbooks for long-term success in the industry.
1. Science and Practice of Strength Training — Zatsiorsky, Kraemer, Fry
This classic bridges Eastern and Western strength systems. It explains how your body adapts to training, how strength is built, and how to balance intensity with recovery.
Why it matters to Hardbody: We use this to design safe, progressive programs for all levels—from middle schoolers to adult professionals.
2. Supertraining — Verkhoshansky & Siff
One of the most advanced texts in the field. It covers every system in the body, every form of resistance training, and how to adapt training to different sport demands.
Warning for coaches: It’s dense, but if you want to lead athletes to greatness, this is your graduate-level manual.
3. Poliquin Principles — Charles Poliquin
Poliquin was a pioneer in individualized training. This book outlines his approach to training frequency, exercise selection, and functional hypertrophy.
Why we reference it: Many of our structural balance protocols and grip choices were inspired by Charles.
Science & Physiology
Why this matters for parents/athletes: Our workouts are designed with your body’s actual biology in mind.
Why this matters for coaches: You can’t write great programs without understanding the systems they affect.
4. Strength and Power in Sport — Edited by Paavo Komi
Breaks down muscle mechanics, neural adaptations, and sport-specific strength.
Why we care: It explains the “why” behind force development — crucial to our Speed + Power training blocks.
5. The Physiology of Training — Whyte & Spurway
A great intro to recovery, energy systems, and how your body changes over time with training.
Why we like it: It bridges the gap between science class and the weight room.
6. Strength & Conditioning: Biological Principles and Practical Applications — Cardinale, Newton, Nosaka
A full breakdown of monitoring, recovery, stress adaptation, and performance programming.
Why it matters: It’s the backbone of our MAP Assessments and athlete tracking systems.
7. Strength and Conditioning in Sports: From Science to Practice — Stone, Wagle, Suchomel, Hornsby
Links theory to practice in the clearest way we’ve seen.
Why it matters: Our 13-week mesocycles, fatigue management, and recovery tracking reflect the frameworks in this book.
Periodization & Program Design
Why this matters for parents/athletes: It’s not just “hard workouts.” Every training block is timed for peak results.
Why this matters for coaches: You need a framework to progress your athletes safely and effectively.
8. Periodization of Strength Training for Sport — Tudor Bompa & Buzzichelli
Outlines the exact phases of training to peak for performance.
Why it’s foundational: Our 13-week macrocycle at Hardbody is directly inspired by Bompa’s methods.
9. Scientific Foundations & Practical Applications of Periodization — G.G. Haff
Merges science, templates, and real-life coaching strategies into one resource.
Why we love it: It’s the most accessible deep-dive on periodization for coaches at every level.
10. How to Write Strength Training Programs — Ian King
Teaches how to structure workouts from scratch with real logic and flow.
Why it’s great for new coaches: This book helps you avoid writing random workouts and start building systems.
Applied Strength Coaching
Why this matters for parents/athletes: These books prove that what we do at Hardbody works in real life — not just in theory.
Why this matters for coaches: If you want to coach in the real world, this is your playbook.
11. Fitness and Strength Training for All Sports — Jurgen Hartmann
A goldmine of forgotten tools and sport-specific methods from the East German system.
Why it’s rare but useful: You’ll find gems in here that aren’t taught in modern textbooks.
12. Developing the Athlete — Kraemer, Ratamess, Newman
A total roadmap for sports performance. Covers everything from testing to team management.
Why we use it: Kraemer’s influence shaped how we integrate data, science, and coaching at Hardbody.
Final Thoughts
At Hardbody, we don’t chase trends. We build from the ground up—science, structure, and systems.
To Parents and Athletes:
If you’re wondering why our program feels different—it’s because it is. We’ve read, tested, and applied the best of strength science so your athlete doesn’t just train harder… they train smarter.
To Aspiring Coaches:
If you want to coach at a high level—or even join the Hardbody team—this is your starting line. One book at a time, you’ll build the tools to lead others with confidence.
