Walking is also the easiest possible thing you can do so if you never push yourself how do you know how far you can go on the track to a healthy life? While you walked I did 65 minutes of hard cardio on the elliptical and burned over 1000 calories. Do you have any idea how rewarding that is? I guess to get the ball rolling then sure walk. I mean I even started my journey walking slow on the treadmill. I progressed way beyond that now and 15 months in I have literally transformed my body from 270 pounds of uselessness to 210 pounds. I have toned my stomach and put on muscle. At 44 I have never felt better, healthier or stronger. I am fortunate enough that I sweat like crazy releasing all the toxins my body wants out. Would I have been happy if I didn't work out much but still lost the weight? Ya probably but seeing what the extra effort can do is mind blowing. I posted my before and after pics on here and when I look at them I still shake my head at what my hard work and dedication was able to accomplish.
