What does a "neutral back and shoulder" position mean to you?
I'm an intermediate road rider, decent with the fundamentals of bike fit and fitness but far from my goals. I've been wondering about what a "neutral back and shoulder" position means to different people.
Do you consciously try to maintain a flat lower back throughout long rides, or do you tend to change up the location of your back's arc?
And, related, do you stretch your shoulders fore and aft, or do you try to maintain the same position? One position allows you to stretch out, and the other gives you more control on the bike and relaxes the shoulders and upper back.
Obviously there's no hard and fast rule, but my goal is endurance riding and longevity (as in age). I'm curious about how people's fit adapt within a long ride. I want to minimize stress and damage to my lower back.
