I have recently switched from a dumb trainer to a smart trainer, an Elite Suito. After trying out all modes, I found out I prefer erg mode for Z2 workouts, warmups and rest intervals, but anything at or above sweet spot I prefer resistance mode.
Switching back and forth on my iPad, especially in an oxygen-depraved state, is finicky and hard. And with the touch interface on the iPad, short cuts are of no use.
So I thought this might be an idea for a feature. What do you all think?
