I have begun with several mini workouts throughout the day, for instance, I have a dumbell in the bathroom for curls, etc while I'm visiting for other reasons. I'll stop once every hour or so for push ups, a set of jumping jacks, or something else. I know that, right now, this will be effective as I've been primarily sedentary for the last many years. Any movement is more than I was doing.
What I am wondering is if anyone has had long term success with mini workouts rather than pushing through an hour at a time.
(I've also added in walks 3-4 times per week, though I'm only up to 1.5 miles each so far, I'll keep going further as I'm able)
