Most athletes know what they do in training…

Few understand what is happening underneath.

Every interval, long run and Hyrox session places demands on your body's energy systems. The challenge isn't simply training harder—it's understanding which systems need to be developed and whether your training is producing the adaptations you're aiming for.

The Engine Room was created to help athletes see beneath the surface of performance.

The Engine Room


The Engine Room was created to help athletes understand their physiology and train with greater precision, purpose, and confidence.

Rather than relying on generic training zones or estimated heart rate calculations, threshold testing allows us to understand exactly how your aerobic and anaerobic systems are working.

These insights help athletes answer important questions:

  • Are you training at the right intensity?

  • Is your aerobic engine improving?

  • Is your body using fuel at maximum efficiently?

  • Is your training producing the adaptations you're aiming for?

  • Are you ready to progress your workload?
