The simplicity of the test is its greatest advantage. Anyone can test oneself. That’s great. I will be recommending it to my friends about whose health I feel most concerned.

This is such a great reminder. Because of my arthritis I have struggled to find an exercise I was comfortable doing but I recently purchased a machine similar to the Power Plate and it has done wonders for me. So every day I get a little bit stronger.

It is so important to do excerise and I know a lot of people like to think about the present but sometimes it is good investing in time for the future. People don´t know how crucial it is to at least go for a job once and a while.

Outstanding article..
America’s have the worst diets in the world of none health food available to them on every turn. I believe this plays a large part.

In my opinion it’s extremely important to be in a good shape. I can’t say that I’m old, I’m under 25. However sport & fitness are my good friends.

I know that according to research, exercising makes you more happy. It’s a fact.

From my experience, I always feel myself better and have more energy after running or swimming.

Fitness is a great thing.

Exercise is recommended to gain weight, to lose weight and also to maintain current weight level. To gain weight, we need to lift weight whereas to lose weight, we need to move our body weight.

When we talk about our body we need to chuck logic and common sense out of the window because our body has its own logic that is quite separate from that of our mind. For example, if we eat less than our daily calorie requirement, logic and common sense suggests that we ought to lose weight. We don’t; in fact the opposite happens – we gain weight! The logic our body follows is that we are eating less probably because of famine or some other problem so the body conserves energy (you feel lethargic and dull), and converts whatever food it receives into fat. It does this because of the human evolutionary history that has been recorded in our genes. As we evolved, humans have been through famine and starvation. This has been recorded in our genes. So when we begin to eat less, the sirens go off and our body takes action to conserve energy and food – a basic survival strategy. We mention this to give you an insight into how our body ‘thinks’.

The generalizations you make in this article are scary, and a big part of the misinformation out there that gets ppl hurt and misguided. Your definition of fitness is bad, and your MSG of more exe is better is terrible.

Fitness also reflects your exercise capacity.Just over 2,400 people died during the study. In the last five years of their lives, the people who had been most fit at midlife spent about 50% less time with four or more chronic diseases than the least fit group and 34% more time with no or one chronic disease.
