On NPR this morning there was a segment on Walking and Working at the same time. I loved the idea of having business meetings that include walking because you are "going in the same direction". I imagine a great deal more would be accomplished if more meetings were done this way.
I already exercise more than 30 minutes a day, but that doesn't include walking. Right now it includes TurboFire and Les Mills PUMP, although my bestie is now a certified Turbokick instructor so we have decided to drop TurboFire for a month so that she can practice teaching. By that I mean I get to be her guinea pig. We did a Turbokick round a few weeks ago and it was a fantastic workout so I'm excited to shake things up.
We will still be doing Les Mills PUMP 3x a week because I still feel that it is the best weight training program I have ever done (and that includes P90X), but we want to have variety in our cardio.
That being said, NPR inspired me to get walking 150 minutes a week. Not because I want to overtrain or burn extra calories, but just for the overall health benefits. My bestie and I work out late in the afternoon, which is fine, but I like getting my blood pumping in the morning (8am type of morning, not 5:30am type of morning). So hopping on the treadmill and getting my early work done at the same time will make me more productive throughout the day.
