The Box Perform 6-Week Challenge is crafted to turn these visions into reality, with a balanced emphasis on nutrition and effective exercise.

How Does It Work?

We use a 3 Step System

Step 1 - Metabolic Testing

Test Don't Guess!


We use something called metabolic testing to help people like you finally break the diet cycle and eat normally without gaining weight.


Our metabolic testing service uses a combination of clinical tests and advanced technology to build nutrition and exercise plans that are tailored specifically for your unique metabolism. Unlike other coaches who simply guess your calories and macros and hope for the best or, macro calculators which are woefully inaccurate.


With our service, we will create a nutrition and exercise plan that is based on your individual needs so you can finally eat normally and achieve the body you’ve always wanted.

1. Test Your Metabolism

From a simple RMR (resting metabolic rate test) we can measure exactly how many kcals you burn at rest. From this we can provide you with the number of kcals (how much food) you need to help you lose weight, but most importantly how much you can eat without starving yourself! Who wouldn’t want to eat more food if they didn’t have to.

The metabolism test is a simple test, which involves you sitting down and relaxing for 20mins. You breath into a mouth piece and using a metabolic cart, we measure the oxygen that you’re breathing in and the carbon dioxide that you’re breathing out. This ratio helps us determine how many kcals you burn at rest. This is called indirect calorimetry. This is the gold standard for measuring calorie burn.

2. Test Your Body Composition

Using the premier body composition analyser, the InBody 270, we measure how much lean mass you have in each body segment, as well as segmental fat and visceral fat analysis. In conjunction with your metabolic data, this body composition analysis helps us to provide a unique nutritional plan and exercise regimen for you to optimise fat loss and muscle gain.

3. Test Your Active Calorie and Fat Burn

Consider enhancing your 6-Week Challenge with our optional VO2 max test. This straightforward assessment accurately gauges your calorie burn and fat-burning capacity. It's a powerful tool that allows us to tailor your fat loss and fitness strategy even further, crafting an exercise plan that's aligned with your heart rate data and current fitness level. Embrace the science for smarter, more efficient results.

What is the Fitness Test?

The Fat Max or VO2 test is a simple exercise test performed on a treadmill or bike, where the speed or resistance increases gradually until you can’t exercise any longer.


The speed is based on your fitness level and can be done either walking or running. You do NOT need to be fit to do this test.

During the test, you will be wearing a mask connected to the metabolic cart. The metabolic cart will analyse the oxygen you breathe in and the carbon dioxide you are breathing out. You will also be wearing a heart rate monitor to gather as much information as possible about your health and fitness. 

From the data, we can accurately assess your calorie and fat burn during activity, as well as being able provide you with exercise sessions to help supercharge both your fitness and fat loss.
