Adding activity to my week

I recently started going to meetings for discussions about health and activity. Today’s question was “how will you add activity into your week?” I added that I plan on adding a quick walk a few times a week, since I found it only takes 10 minutes to get around the block with Molly. Less if I go alone, since I don’t stop to smell the bushes. The coach laughed and asked why I didn’t. You know, I didn’t have a good answer.
