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.
