Sure you are not.
My ‘personal trainner’ is not an integration, but a guide to combine several integrations to suit your needs, and some custom cards to build a nice interface.
You can follow this guide (only in spanish for now). Next version will be in english too.
I thought it might be, just didn’t have time to properly read it.
I’ll wait for the English version, so please let me know when it’s available 
Its easy enough to follow with Goigle Translate
Have you managed to make sensor from garmin intergration, last activities attributes ie pace, time etc?
