Most Garmin watches can guide your workout steps by speed or heart rate.
We recommend connecting:
The Garmin service to send recorded activities back to TrainAsONE The Garmin Training service to push your TrainAsONE workouts to the Training calendar on most watches
Alternatively we provide a TrainAsONE Garmin  app, which can adjust some settings and download your next workout directly to some watch models, and you can also download workouts via a computer.
