I am a Garmin user and I have both the Fenix 7X SS and the Garmin Edge 530. When I go out on my bike to train (both cyclocross, racing bike or mountain bike) I carry the Fenix 7X SS on my wrist because it has the FirstBeat metrics higher than at Edge 530.
Having said that, I propose an implementation to Garmin. I use to train with the suggested workouts of the day that the Fenix 7X SS offers me according to my physical state and they work very well. I would like Garmin to allow me to send those workouts from the Fenix 7X SS to the Edge 530 to have them on a larger and better visible display, even if, at the end of the workout, I would keep the data recorded by the Fenix 7X SS and delete those of the Edge 530 that I would have needed it only for an optimal view of the information, which on the Fenix are really uncomfortable to read when using a bike.
So my proposal for Garmin would be to create a button that allows the export of the training of the day from the Fenix 7X to the Connect platform or to send it to another device which, in this case, would be the Edge 530.
