Our Tests

Two Tests. Total Clarity.

Whether you want to understand your health, improve performance, or both — we have a test for you.

🛌

Resting Metabolic Rate

Understand exactly how many calories your body burns at rest — and what that means for your weight, energy, and long-term health.

  • True caloric needs for any goal
  • Metabolic dysfunction risk score
  • Fat burning efficiency at rest
  • Heart rate variability (HRV)
  • Lung utilisation at rest

What People Are Saying

★★★★★

I'd been training for an Ironman on guesswork. The VO₂ test showed my zones were completely off — I was going too hard on easy days and not hard enough on intervals. Fixed that and knocked 14 minutes off my half-iron time.

Triathlete & cyclist
★★★★★

I was eating 1,400 calories thinking that's what I needed to lose weight. The RMR test showed my metabolism was actually burning way more than that. I'm eating more now and finally dropping body fat. Wish I'd done this years ago.

★★★★★

Ran my first sub-40 10K after adjusting my training zones from the test. The report was dead clear — no confusing graphs, just 'here's what to do.' James was brilliant at explaining everything too.

🏃
Dan P.
Club runner
★★★★★

Not a competitive athlete at all — just wanted to understand why I was always tired by 2pm. Turns out I was barely burning any fat at rest. Changed my nutrition off the back of the results and my energy is so much better.

What Happens Next

A Plan, Not Just Data

Every score comes with specific recommendations across exercise, nutrition, and lifestyle — so you know exactly what to do next.

🏋️ Exercise

Resistance Training

Strength work builds muscle mass, increasing oxygen uptake and metabolic rate — directly improving your test scores over time.

Interval Training

Zone 4–5 work improves heart function and lung capacity, pushing your VO₂ Max higher with every block.

Zone 2 Endurance

Low-intensity aerobic work trains your cells to absorb and utilise oxygen more efficiently across the whole body.

🥗 Nutrition

Beetroot & Nitrates

Foods rich in nitrates dilate blood vessels, boosting oxygen delivery to working muscles during exercise.

Iron-Rich Foods

Adequate heme-iron supports healthy haemoglobin and red blood cell production — essential for oxygen transport.

Calorie Precision

Knowing your RMR means your nutrition plan is built on real data, not generic calculators that miss by 300+ calories.

🌙 Lifestyle

Exercise Timing

Completing high-intensity work in the afternoon aligns with your natural cortisol curve for better output and recovery.

Sleep Quality

7–8 hours of quality sleep directly improves physical recovery and raises your VO₂ Max ceiling over time.

Body Composition

Reducing body fat by just 5% can meaningfully improve your VO₂ Max — and your test tells you exactly how to get there.
