Walking rather than sitting or even standing has helped me with my back problems after having had two surgeries for a herniated disc. The constant motion helps prevent me from developing problems that would always develop from those static positions. Additionally I tend to pace when I think and this means I can stay at my desk while puzzling something out. The fact that I can burn a thousand calories on an extended day of focus is just icing on the cake. I see my treadmill desk as something that helps me work, not a substitute for the gym. Maybe dial back the judgement and "harsh wording" in the future, or at least talk to people before developing and/or sharing such a strong negative opinion.
