Who It's For

For people who want real change.
With a clear direction.

Burnt-out professionals
Keeping up but running on empty. Tired after sleep. Reactive instead of focused. More effort isn't working. You need to understand why.
Athletes hitting a plateau
You push hard. Your system needs to recover harder. The edge isn't in more volume. It's in the details most people miss. A specialist will find yours.
People struggling with sleep
Enough hours but waking up tired. The issue isn't duration, it's regulation depth. A specialist will tell you exactly where it breaks down.

Questions, answered

FAQ.

How accurate is a 20-minute test?
The CO₂ BOLT test and the Stroop test are validated in clinical and sports-science research. Combined with your wearable data and lifestyle questionnaire, they give a precise picture of your system today. They're a starting point, not a final word. That's why a specialist reads the result, not an algorithm.
What if I don't have a wearable?
Not a problem. The test still works without one. Your CO₂ tolerance, Stroop test, and lifestyle context give your specialist what they need. If you do use an Oura, Whoop, Apple Watch, or similar, your 7-day HRV trend makes the picture sharper. Or pick Report + Coaching + Polar 360. A wearable is included.
Can I do this from anywhere in the world?
Yes. All tests run from home, guided step by step. The coaching call is live video. If you'd rather do it in person, sessions are available in Sliema (Malta) or Fréjus (France) with a BYOR-trained specialist.
How is this different from Whoop, Oura, or ChatGPT?
Whoop and Oura measure you. They don't read you. The score doesn't know your stress, your focus, your real life. ChatGPT doesn't have the data. It just sounds confident. A BYOR specialist reads your biometrics in context and delivers a tailored routine. Not a dashboard. Not a chat. A real specialist, a real routine.
How long until I see a difference?
Most people feel a difference in 2 to 3 weeks once the first habit is locked in. Your habits are added one at a time, so each one settles before the next stacks on top. Short-term wins early, durable change as they build.
Is this medical advice?
No. BYOR is informational and lifestyle-based. It's not a diagnosis and doesn't replace medical care. If anything in your report suggests you should speak to a doctor, your specialist will say so clearly.
What if it doesn't help me?
Your specialist works with you until the report makes sense and you know your next step. That's the standard. If something is still unclear after your call, reach out and we make it right.
