yesterday I jumped on the trainer for the first time in ages, and what I noticed most was that my RPE was so much higher for the same heart rate than outside. What can cause this?
I know that the monotonous strain (no coasting), lack of wind, somewhat higher core temperature, can all contribute to this higher RPE, but I’m worried that I’m not getting the same benefits if I’m working out at a lower heart rate all the time when inside.
To give an idea, when I ride outside I would give 150HR a 4 out of 10, inside this was easily a 6.
The core of the question: for max benefits, should I ride to RPE or HR?
