It would be of great use to me for Zwift to be able to automatically adjust trainer resistance WITHOUT ERG mode.
I sometime do strength sessions using short intervals at high power (150-200% FTP) but V low cadence (45-60 rpm). Whilst I currently do these with ERG mode, it can be difficult to hold such a low cadence at that effort level; whilst avoiding the ‘spiral of death’. Yes, I could use the up/down keys to alter resistance manually, but this is not practical, particularly toward the end of a hard interval.
What would be ideal is to have the trainer resistance adjusted automatically but without controlling for a fixed power - just increasing the resistance to an arbitrary level. I could then set this ‘arbitrary level’ in my workout plan and with a bit of trial and error get it to set the right amount of resistance for my intervals, but without the difficulty of avoiding the ‘spiral of death’.
These type of intervals are very much bike specific weight training, and I find use of zwift and a smart trainer a very effective way of doing these, much easier, more controllable and practical than sprint intervals in a big gear on the road, but it would be better still to just have the automatic big increase in resistance but without the associated difficulty of ERG mode.
