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.
