I am looking to buy a treadmill. I walk almost everyday about 20 minutes or more but I have just gotten to the point I just do not feel comfortable walking alone anymore. We live in a small town no crime but I guess I am getting older and don't feel I can move as fast as I used to. I have ask people to walk with me and that lasts a couple weeks and then they don't want to anymore. They just don't have time. Neither do I but I make time!!! I have tried out several treadmills in the stores and I don't know what is best. I know that I walk at a pretty fast pace and started even jogging about a year ago so I want one you can jog on if I want to. Any suggestions or tips would be helpful.
