Weight loss is more about figuring out your unwanted behaviors rather than numbers on a scale, chart or treadmill. Figure the whys out and you will have staying power. Don’t and keep getting more out of shape.
Over the years most of us who are out of shape and want to lose a few pounds and feel a little better about ourselves, developed many different behaviors toward exercise and food. Some are good ones, but most are just barriers we have built in our minds. I guess you could also chalk it up to pure laziness.
