I hope next step going forward with Garmin Coach would be integration of Strength training into Run or Cycling training.
At this moment we are not able to have two trainings active for the same time. It should change with some "interlocking"
I mean specify in one training eg Run when you want to go outside and offer only other "available" days for strength training.
Both should be adjusting workouts to overall training status.
I am going to share this via https://www.garmin.com/en-US/forms/ideas/ , and encourage you to do so if you find this interesting.
