How these pages are made

Every page starts with the answer, lists its sources and shows when it was last reviewed. Where a number doesn’t come from a study but is Tarvo’s own choice, the page says so.

Written by Yannik Muth, who builds Tarvo. The same rules run in the app.

Tarvo does the math for you.

Every target in Tarvo follows the rules on these pages. You train, Tarvo sets the next set.

One email when Tarvo launches. Nothing else. Privacy
