Rambling on and on about exercise

I didn't exercise yesterday but today is the beginning of another week.  I exercise on average of 10-15 minutes a day.  I may have to change my exercise habits and my schedule.  I walk.  That is all I do.  I walk.  Walking is a good exercise.  I am not perfect so I don't always start the video off well.  I have to catch up with the exercise instructor depending on the video.  I have a pedometer but I don't know how many calories I have burned walking.  Maybe I should walk around the block or in the backyard. I know I am just rambling on and on and on, but I like to walk.  I plan to go shopping today and as I know full well, that in itself is a workout.
