That works pretty well for regular power target jumps. For larger jumps to say VO2 Max and above, I find that slowing cadence (say around 90 rpm from my normal 97 rpm), until the trainer start to add resistance for the new target, and then accelerating to my desired cadence (say 110 rpm for the VO2 interval).
- This initial “slow” cadence makes the trainer add resistance during the recovery step of the interval. It sets the resistance to a “higher resistance” due to the lower cadence. When I jump on the cadence to rev up for the interval, the “step” that the resistance unit has to climb is less than if I was already spinning at my higher cadence. That quick cadence acceleration closes the gap and gets me to the higher target power sooner.
