I tried it, I liked it. Listening to someone else talk is a little more engaging than listening to music, for me. I like to take outdoor walks to break up my work day, not a replacement for "real" exercise when I prefer the AF+ coaching and good music. And AF+ coached workouts are not a replacement for my gym membership, when I like to do my own thing. Layers of healthy options are good.
This is like a mini podcast, but I have never done the research to find the good podcasts and never got in the habit of listening to them. This just popped up on my watch and was easy to try. Now I feel like I have to go take a walk if I'm interested in one of the speakers, and that's good for my health.
Regarding the complaint that on Day 1 there are only 4 choices, um, they will be releasing new ones every week. Not a valid complaint.
