Calibrate. Fit the
Reserve Method to You.

Five instruments. Each one provides critical information. Most programs provide one program to follow, no matter where someone is in their fitness journey. Sink or swim.

Your Information Stays Yours

We do not collect any personal information. None of your input, results, or information is stored with Reserve Fitness + Cognition. There is no server or storage device. Every result these tools produce is written to the browser on the device you used — and stays there.

That is a deliberate choice. Your health information is personal, private, and privileged. Deciding who sees it is not a preference to be negotiated away in a settings menu — it is yours to hold. The tradeoff is real, though, and you should know it: clear your browser data and valuable history and trend data is gone. Use the export button in each tool, and keep the file somewhere you trust.
