I’ve begun walking for exercise, again. Right now it’s so cold outside I’m walking inside on a treadmill. I’ve just begun so I’m setting no records. I began a week ago walking 15 minutes at 2 mph. This weekend I started walking 30 minutes at 2 mph. However, yesterday I began having pain in my left knee and left hip; the one I had replaced. This morning I stopped after 17 minutes. I keep reminding myself I need to work into this gradually and not push myself into an injury that will force me to stop. Being patient and gradual increases will get me to where I want to be: able to hike small distances to put myself in a place of greater potential.
