@RayKray that's great to hear and fascinating!
Yea, I don’t know the answer. My bias is that I think an individual's attitude to exercise as a whole is unlikely to be innate. Certainly, immediate feedback (heavier, faster, further) is more motivating than distant goals like ‘be healthy’ and ‘reduce disease’. Long-term the most motivating experience is feeling good prior to, during and immediately after exercise - this is where a lot of people get it wrong. Too much, too hard, too soon.
Overall, we see in exercise science that there’s evidence for something called self-efficacy transference - gaining competence in one area of exercise leads to self-belief in other activities. So, as you get fitter and more skilled, you get enjoyment through trying more and new activities. But, it requires that you stick at something and make progress long enough to get fitter and skilled.
@peelyjuice yea, people all have what we call different ‘antecedent preferences’ for exercise i.e. liking/disliking group exercises, showing off/shying away, empowerment/damage, pride/honour/shame/guilt, competence/incompetence and interest/boredom. Often shaped by experience in PE class or elsewhere early in life.
