Plan, measure and shape training safely.

A collection of browser tools and technical papers for training — from children learning to ride a bike to club and performance sport. Everything runs in your browser: no account, no tracking, no data transfer.

Test operation. All tools have an English interface; each link opens the English version. The technical papers are currently in German.

For whom

Parents and grandparents, coaches, PE teachers, clubs, personal trainers and athletes — from recreational and senior sport to performance sport. Each tool says who it is for and where its limits are.

How it works

Open a tool, enter your values or press »Example«, and save the result as a file if you want to keep it. Files can be combined in the training folder and passed on — nothing leaves your device unless you send the file yourself.

Languages and regions

sport-trainer.eu is the international edition in English. The German edition for Austria and the DACH region, with Austrian law, standards and references, is sport-trainer.at. Calculations, rules and safety notes are the same in both.
