The Chester Step

Chester Step Test Software (CST2)

CST2 is the latest version of the Chester Step Test - a web app that is a simple fitness test involving stepping onto and off a low step in time to an audio beat to predict aerobic capacity from submaximal heart rates.

We've refined the original Chester Step Test to add specific measurement modes for cardiac rehabilitation, firefighters, commercial divers & personal fitness trainers.

CST2 tests improve reliability and validity over the standard CST.

Chester Step Test is being used globally in a wide range of occupational, clinical and community health, fitness and wellbeing scenarios.

The new CST2 web app that you can access from your laptop, tablet or phone.

  • Heart rate collection every minute improving the reliability and validity of test results
  • Integrated PAR-Q, Pre Exercise & Contraindications Questionnaires (Contraindications on Cardiac Rehab. Edition Only)
