Start AssessmentProfessional methodology
Built for professional fitness assessment
These tools are designed to make established testing methods easier to administer, calculate and interpret without replacing the underlying protocol.
01 · EVIDENCE
Published methods
Calculations and reference values are based on published methodologies, equations and datasets rather than invented scoring systems.
02 · PROTOCOL
Technique matters
Each assessment explains how the measurement should be performed because changes in equipment, position or protocol can alter the result.
03 · EQUIPMENT
Measurement + equipment
Where appropriate, each tool connects to professional testing equipment supplied by Cartwright Fitness.
