I currently use workouts on an Interactive Home Trainer on my Edge 530, and they works fine. One thing I noticed is that when the step target is power, suppose 5 min in Z3, the resistance of the trainer adapts, forcing to average the Zone value. That's classic ERG mode. Example. if Z3 is - say - between 240 and 280 W, the resistance will bring you to 260 W, no matter how fast or slow you're pedalling.
This is generally ok, but I wonder if there are ways to change the target inside the Power Zone during the workout. Imagine that I want to average 275 W instead of 260 W for that step. Is that possible?
Thanks
