SO i found a nice trail I can walk or run. Eventually I want to incorporate some running into my time on the trail, but right now I am mostly walking at varying speeds, depending on what BPM the music is that I am listening to. How many miles should I look to walk for exercise? Will the results equal out if I add weights to the walking? I don't like running very much unless I'm on a treadmill (no obstacles or inclement weather to worry about). I went through some threads in here about running, pacing, and timing. I tried some of these things last summer with a change to the diet but did not see results like I did when I just did cardio and some weight lifting. I lost access to my gym so I have to find something else to substitute for now. Am I wasting my time walking?
