Four ways to test

Built on published ACSM algorithms.

Every VO₂ calculation is grounded in the American College of Sports Medicine's published algorithms — so your data stands up to any clinical or GP report.

Jog / Run

Speed (kph) + gradient (%). Suitable for fitter clients and athlete assessments.

Walk Uphill

Speed (kph) + gradient (%). Ideal for cardiac, deconditioned, and rehab clients.

Cycling

Power output in watts. Reproducible, low-impact, and excellent for tracking progress.

Step

Step height (cm) + cadence (ascents/min). Minimal-equipment testing for any setting.

Source: American College of Sports Medicine (ACSM) published algorithms — the international standard for exercise prescription.

"

We have been using fit.test on all our clients for 4 years now. We find it fantastic for all aspects of EP work — from reporting to GPs to showing progress to clients. We could not recommend Steve's program for cardiovascular testing highly enough. You will not regret using this simple, effective and accurate program for each of your client assessments.

"

Our team of AEPs has found immense value and ease of application using fit.test for reproducible and individualised assessments of aerobic fitness. The many GPs we communicate with have valued the clear objective feedback — and the assessment process easily fits within a standard initial or subsequent GPCCMP appointment.

"

fit.test has been a valuable tool for our clinic in delivering comprehensive graded exercise testing for both athletes and clients with cardiac conditions. It provides an easy-to-use way of assessing cardiorespiratory fitness and determining a safe, symptom-free heart rate range. The program design feature is particularly useful — I highly recommend fit.test to any clinic.
