Personalized Exercise
As the start of every year, many of us promise ourselves that a certain number of times a week we will go to the gym or attend an exercise class. But finally many of us just struggle to fit exercise into our lives, or start off well and then give up. Why do we have a good plan at the beginning and fail to achieve it in the end? How can we deal with the problem?     
It is important to determine your motivation first. Are you mainly interested in de-stressing or in getting fitter? If your goal is relaxation, then ask yourself if you want to do it energetically.     If you have a calmer style, you can do something quite different. You could choose solitary exercise, such as walking the dog or doing some gardening.     There are quite a lot of them, such as walking and running groups, dance classes, etc. On your own, you could go horse riding or swimming, or just download fitness exercise programs and do it at home.
    If you have free time at the weekend, you could book some time with a personal trainer, who can come to your house, or you could meet him at the gym. If your life is not as regular, you could choose the next couple of minutes you have to try an exercise DVD, or put your running shoes on and run for any length of time.
As you see, everything counts when you are doing exercise. Whatever your lifestyle is, you will be able to have something that suits you.    Just sit down with a cup of tea, read this article again, and have a think about your options. Then finish the tea, get up, get going, and don’t stop.
