More on Steve.

Steve became New Zealand’s first qualified personal fitness trainer in 1987 and has been coaching, programming, and writing about training ever since. The certifications kept stacking — ISSA Master Personal Trainer, Fitness Nutrition, Group Fitness, Strength & Conditioning, Sports Nutrition, and Transformation Specialist — but the core focus has stayed the same: explaining the why behind every exercise, set, and nutritional choice so the reader can make their own decisions when there’s no coach in the room.

That education-first approach is why Steve writes the bulk of the exercise-alternative guides on this site. They’re some of the most-read pieces we publish, because they answer the practical question every home-gym lifter eventually asks: “My gym doesn’t have a cable crunch / pec deck / battle rope. Now what?” Steve’s answers come from 35+ years of programming around limited equipment for real clients.

Outside training, Steve is a working historian and the author of more than thirty books on great battles throughout history. The crossover is more useful than it sounds — long-form research and writing demand the same disciplined, source-led thinking that good training programmes do, and the work has shaped how he edits a guide before it ships.

Steve trains and writes from a small home gym in Tauranga, New Zealand. He sees Strong Home Gym as the place where lifters from anywhere — whatever their gear, whatever their experience — can learn the principles that work in any setup.

Steve's qualifications.

Where Steve's work has been cited.

Most fitness writing tells you what to do. The work that actually changes people is the work that shows them why — what the research says, what the rationale is, and how to make their own decisions when they're alone in the garage.
