How Can We Help?

Metabolic and VO2Max Testing.

Metabolic testing and VO2Max Testing is the gold standard assessment for measuring how many kcals you burn (your metabolism) and the type of fuel you use (e.g. fats or carbohydrates). It is used to help assess your fitness levels, generate personalised training zones and identify your fat max.

​

Our VO2Max and RMR tests gives you the most comprehensive and insightful health assessment allowing us to develop an accurate nutrition and workout plan to help reach your goals.
