Do all of you who stretch and see chiropractors and massage therapists and use foam rollers and so on do so because of injuries? Asking because I've never stretched, etc., etc., in 50 years of riding.

For myself, I've always found riding a bike in a nearly flat-backed position leaves me as limber as I need or want to be. I do have an old lower-back injury that gives me problems every once in a while, as well as arthritis in one elbow that I broke twice, but the discomfort always goes away after a few days without my attempting to do anything about it.
