Poofie:

I read your post here. I have found that, while walking/treadmill/cardio is necessary, weight training is also necessary. You have to do BOTH. I do my weight training (circuit training) and immediately do the treadmill. I am up to four workouts a week.

My program was designed by a former Mr. America, who is the head trainer at my gym. It works.

In addition to fat loss, you need to build muscle. Walking will not build muscle. It will only burn fat.
