Yeah, running. Great idea. Did that years ago and ruined my feet with it. They still bother me today. Not recommended, especially not if overweight. Pick any other exercise. Preferably one that does not multiply your body weight by gravity and crushes your own skeleton under it.
Hometrainers (is what we call them in Germany, stationary bike?) work fine. You can even mount your eReader on it. Not recommended for real bikes as you have to actually see where you're going with those. Everything else is a motivational issue.
