I don't generally understand these surveys. This one seems to indicate the term "non-responder" is not just unhelpful, but possibly damaging.
"Thus, just because an individual does not improve their VO2max or 1RM with training, this does not mean that they have not derived a multitude of other benefits from exercise, many of which, such as increased social interaction seen in community exercise settings"
What I don't see in this survey is anything related to "off the couch" improvements, which is clearly what we are talking about. Neither myself nor GP said we went from regionals to nationals. We went from cigarettes and beer to recreational riding. I have a hard time believing those gains aren't available to almost everyone. But, I didn't find a study so it doesn't exist :)
If you look at all the positive benefits of exercise you find very few people who don't get some positive benefit from exercise whether that's better insulin sensitivity, better vO2 max, better cholesterol, or weight loss.
But when you look at one specific benefit of exercise such as the endurance required to accomplish these feats you find far more non responders.
In an attempt to clarify "decent amount", maybe this helps? https://link.springer.com/article/10.1007/s40279-018-01041-1
