Oops. Started yesterday as had not been following the plan outlined here but had been thinking of increasing my walking for some time. It is a part of my broader "Healthy Lifestyle" initiative that I have on the go which includes 3 components - physical activity, nutrition and the mental aspect of it. Each of those have sub components such as mental includes social and mental health aspects.
I have adapted my approach to concentrate on distance/steps to start as I cannot walk for any length of time and only for a distance of less than a block continuously. I also will only doing it 5 days a week for several reasons - (1) to avoid overloading myself as I am busy working on other aspects of my lifestyle improvement plan and (2) avoid burnout. As usual I will reviewing this plan periodically as I go as that is usually required to keep on getting better at what I'm doing and adjusting for issues that arise.
