Conceptual understanding for everyone. Applied execution for serious practitioners.
The Power Playbook is the foundation of the Evans Velo Zone™ system–published in two distinct editions for different levels of depth and application.
Seeing the Power System introduces the philosophy behind modern power development–shifting how coaches and athletes understand velocity, fatigue, and repeatable output across the force-velocity spectrum.
The Practitioner Field Manual is the complete technical reference, translating that framework into applied diagnostics, training zones, and decision-making for real-world coaching.
One edition changes how you see performance. The other shows you how to apply it.
