Ready to train
When setup is complete, you will see a clear “ready” state before the first breath.
Baseline breath
A baseline breath establishes today’s reference for training.
Baseline in progress
Keep steady effort; the display updates pressure, time, and power in real time.
Baseline complete
At the end of the baseline breath, you can accept or recreate if needed.
Baseline accepted
With baseline accepted, the training target is shown on the screen.
Training breath
Aim to meet or exceed the training target on each breath.
Rep complete
Completed breaths are summarized so you can see how each rep met the goal. Continue through the prescribed breaths; rest intervals and prompts guide the session.
Performance Warning
If a breath falls below acceptable levels for the session, you will be asked to stop training so you can recover safely and keep quality high.
