No one mentioned biking, from what I saw. Get a stationary bike for at home. Cover the faceplate that shows time and distance. You'll be riding that for an hour before you know it. A good starting pace is 12 miles in an hour. That is one mile every five minutes. I can do 14 in an hour on lower resistance but doing 12 an hour on higher resistance is "better" as you go on.
