Keep a stroke-level logbook for every workout

Ergon programs any workout and saves data about every stroke. A silly amount of effort has gone into making Ergon robust to Bluetooth and internet connectivity blips.

Questions

What happens when the trial ends?

Subscribe to keep Premium, or drop to Free and keep logging. Nothing is deleted either way.

Do I need a Concept2 Logbook account?

No. Ergon talks to the PM5 directly. Link a Logbook account to import your history and keep both in sync.

Which machines work?

Any Concept2 erg with a PM5: RowErg, BikeErg, SkiErg, Dynamic and Slides.

Can I take my data elsewhere?

Yes. Pieces you row in Ergon go back to your Concept2 Logbook, and any piece exports as a FIT file. Export is free. With Premium, the file also carries the force curve for every stroke.

Can I cancel?

Yes. No retention screens, no emails that ask you to reconsider.

Count every stroke.
