Measure fitness with confidence
Protocols, calculators, equipment, software and practitioner support for consistent fitness testing. Start with the physical capability you need to assess, then move from a single test to a repeatable professional workflow.
Choose what you need to assess
Each assessment area brings together the relevant tests, protocols, interpretation guidance, calculators and equipment. Choose the capability first; then choose the method that fits your population, setting and purpose.
Step tests, shuttle tests, intermittent running and direct or indirect VO₂ assessment for cardiorespiratory fitness.
Grip, back and leg dynamometry and other objective methods for assessing muscular strength.
Jump and explosive-performance assessments for lower-body power and related performance measures.
Repeatable flexibility and range-of-movement assessments, including sit-and-reach protocols.
Skinfolds, anthropometry and professional body-composition methods for estimating and monitoring physical composition.
Role-relevant assessment programmes designed around repeatable methods, clear records and consistent administration.
From one test to a complete assessment system
Use Cartwright Fitness at the level you need. A practitioner may only need a protocol or calculator; an organisation may need equipment, repeatable workflows, reporting and competency management.
Protocols & guidance
Understand how a test is administered, what it measures, how results are interpreted and where its limitations sit.
Free tools
Use practical calculators and assessment tools without needing software or an account.
Professional equipment
Find equipment for step testing, dynamometry, heart-rate monitoring, metabolic testing, spirometry, anthropometry and more.
Cartwright Assess
Run repeated assessments, generate reports and support consistent team workflows without forcing you to store participant data.
Our flagship assessment: the Chester Step Test
The Chester Step Test is a progressive submaximal assessment used to estimate aerobic capacity from the heart-rate response to stepping exercise.
Cartwright Fitness develops the official Chester Step Test software and works directly with Professor Kevin Sykes to support the test, its resources and its continued professional use.
The complete ecosystem includes the protocol, calculator, CST2 software, equipment, heart-rate guidance, research and validation, training and practitioner competency.
Running assessments across a team or organisation?
Cartwright Assess adds the professional workflow around repeated fitness measurement: unlimited team members, optional participant-data storage, anonymous assessments, PDF reporting and a growing library of included assessment templates.
If an assessment you need is missing, you can request it and we can add it to the library.
Good testing depends on more than the test itself
Reliable fitness assessment depends on appropriate test selection, clear participant preparation, standardised administration, suitable equipment, consistent scoring and careful interpretation. A score is only useful when you understand the protocol and the context in which it was produced.
That is why Cartwright Fitness connects assessment guides, protocols, calculators, equipment, software, research and practitioner training rather than treating each test as an isolated page.
