One way I get a good workout from a walk is to listen to some good music which is set about 120-130 beats a minute. I keep in time with it and walk a part of my neighbourhood which has some steepish hills.

I keep the pace both up and down hill. I never knew walking was such intense exercise till I started doing this.

Keep up the good work.
