If you spend most of the rest of the day sitting — in your car, your office chair, on your sofa at home — you are putting yourself at increased risk of obesity, diabetes, heart disease, a variety of cancers and an early death. In other words, irrespective of whether you exercise vigorously, sitting for long periods is bad for you.The last straw for me: I painted my ceiling beams and after stepping up and down off a kitchen chair more times than I can tell you, I jammed my knee and could hardly walk. I got mostly better, then got on my elliptical trainer and the knee got terrible again.
So in a fury I went out and bought an inexpensive home treadmill from Walmart, set it up, and - since I'm a make-your-own type - built my own "work station" for free. Since then I've spent quite a lot of happy time on the treadmill, mostly reading books I've wanted to "get around to" for quite a while, but also working on my laptop, which fits securely on the treadmill desk.
