How to get snatches of activity throughout the day.
Walk around dining room table doing intervals, walk slow for 1 minute, walk fast for 1 minute, jog for 1 minute, continue this cycle for 10 minutes. Walk/Run up and down stairs- Walk up and down 1 minute, run up and down 30 seconds, to 10 minutes.
I work from home. I don't always have the car to go to the mall to walk, nor is it convenient to walk around the neighborhood. I do snatches of exercise throughout the day up to 30 minutes. This can be in 3 to 10 minute segments. My heart monitor shows 250 calories burned on average.
