The western modern world has brought with it amenities that we find very hard to resist, like our car of example.
In the United States, in a modern city like Los Angeles for example, we have brought the idea of a car and convenience to a new level; we drive to the corner store, we circulate the parking lot over and over again to find the closest parking spot, we take the escalator to the gym so we can spend 20 minutes on the stair-master. All we need to do in order to stay in good shape is to forgo those behaviors and start walking.

That is the main reason, expert believe, the percentage of obese people is so high in the United States. This and the fast food restaurants.

Walking is one of the best aerobic exercises that we can do without it costing us any extra money and taking just a little bit more time. It is a healthier activity than jogging which can be very hard on your knees because of the constant pounding on the pavement.

We all know there are many reasons why we should exercise: to feel better, to get our youthful stamina back, to lower cholesterol, straighten our heart, muscles and bones and to combat stress and depression.

During strenuous exercise our brain increases the production of serotonin which in turn elevates our mood and helps us stave off hunger and make us lose weight. But how to get yourself motivated to exercise and stick with it?

The first point is to be realistic. Set up goals that are within reach. Do not start with exercising hard and for a long time the first time around. That will only cause pain and discomfort and you will try to avoid it the next time.
