I know that regular exercise is a major, major aspect of weight loss, and I don't have a problem with exercising. My problem is that I can't afford to join a gym (there's only one in my area, so they have a monopoly, and their prices reflect that!). So my exercise comes solely from walking.
I walk every single day, for an hour. I try to vary my routes, so that I can incorporate some hills into my routine, and I walk pretty fast (for example, I cannot carry on a conversation while I'm walking.) I'm not totally sure of my speed, but I think I'm at about 2.5 miles an hour.
I guess what I'm wondering is: Is walking really enough in terms of exercise? I keep hearing how important weight training is, but honestly, I'm not -- really into that.) Eventually I would like to work my way up to jogging/running, but I need to see my doctor first (I have early-onset osteoarthritis.)
So I guess I'm just looking for some opinions from people who are farther along in their weight loss journey than I am. Has anyone had success with walking alone? Or am I going to be forced into joining a gym just to do weight training?
