Doing Low-Cadence intervals on a trainer vs on a hill?

It does a good job of outdoor climbing, a couple of tweaks I do to better emulate:

  • trainer or flat road, just “engage the glutes” which for some can be easier said than done
  • hands on hoods, just like how I climb

Inside I vastly prefer how Kickr sim mode provides more and varying resistance. Outside on real HC climbs, even if the road is fairly steady 300 feet per mile, my cadence varies even if power is steady.
