Avoiding the heat in my old-age. I read an interesting HIIT article focusing on heart-rate ranges over one minute intervals governed by RPMs instead of Time. Since Aurora has an RPM window I gave it a try.

The article was clearly not written for old folks since it talked about 100 RPMs & I have topped out in the 70s at my best — which I believe is how AirBikes are designed. I aimed at stead rates of 50-54 and accelerated rates of 60-65. Before I have seen my rate after a sprint drop into the mid 40s so I kept an I on that. “Resting” above 50 RPM is tougher than I thought.

I’ll see if the heat will let me outside or not. Perhaps only Aurora thus week.
