About PerformanceOpti

PerformanceOpti

PerformanceOpti is a library for people optimizing their performance — in training, nutrition, and business. We publish full books, condensed classics, and hand-picked podcasts, all built around the same idea: fewer rules, better defaults, and ideas you can actually use the week you learn them.

Most advice in this space is either too generic to act on or too dense to finish. We aim for the middle: short enough to finish, specific enough to change what you actually do.

The core books

Published by Dr. Hamza Z, MD

The three core training, nutrition, and recipe books are written and independently published by Dr. Hamza Z, a medical doctor, registered nutritionist, and lifelong athlete who spent years watching the same thing happen from both sides of the exam table: patients and clients got a plan, followed it, and lost the results within a year — because no one had taught them the why, only handed them a protocol. These books are the why, grounded in clinical and nutrition training and tested on his own training log — distributed through PerformanceOpti's library alongside everything else PerformanceOpti publishes directly.
