I do not even consider it exercise unless I am hiking a mountain. Lifting is what I consider my actual workout. Also 45 minutes of walking would do nothing for your figure if you had a natural tendency to overeat. Your walk burns maybe 100 calories.
There are aspects of walking you don't appreciate. It is an exercise you can do as you age. Easy on the joints. And if you walk fast, 16-17 min mile, you are getting a workout in esp if you find some hills. And while you are out walking, you aren't consuming calories.
