2. RMR Test

The Resting Metabolic Rate (RMR)  test determines how many calories your body burns at rest, which will help you us provide you with an accurate assessment of how much you need to eat based on your goals.


3. Fat Max Test

The fat max test is an exercise protocol that measures the use of carbohydrate and fat for energy,  which can help determine which intensity of exercise is best suited for increased total fat oxidation (burning). This can be useful for endurance athletes training for long distance events (70.4, ironman and ultra) and individuals interested in body composition.




4. VO2 Max Test

A VO2 max is a test of aerobic capacity. Having a high VO2 max is a prerequisite for any successful endurance athlete. The VO2 max test enables us to accurately gauge your aerobic (fitness) levels,  pinpoint heart rate zones and thresholds, and monitor the effectiveness of your training.


5. Debrief Session and anlaysis

After your testing you will receive a debrief session to properly understand your data, so you are able to implement our recommendations into your training and nutrition plan.


6. Supplement strategy

Based on your results and goals, we will provide you with a supplement strategy personalised to you.
