Program design is well established in principle, but humans are complex, and adaptation rarely follows a linear path. Similar programs can produce very different outcomes, leaving many decisions about exercise selection, progression and modification based on perception rather than evidence.
The Practitioner's Guide to Program Design is a framework for identifying the physical qualities that matter, measuring them reliably and using objective feedback to guide progression. It covers adaptation, feedback loops, technology-informed periodization and session structure, with case studies from elite and developing environments.
