Our sedentary lifestyles has led to our becoming overweight and sluggish with a plethora of diseases taking root and unfortunately bringing far too many people to their early demise. It is then suggested that a rigorous but smart exercise regimen be engaged in by everyone regardless of age.
The results of just a simple change in lifestyle can be dramatic, often in just a week or two. The human body is built for endurance, strength, and speed. It has highly efficient systems built into it to maximize the nutrition and exercise it gets. That being said you'll find reams of recent medical data that supports what was said centuries ago by philosophers and physicians that the value of good exercise, a proper diet, and good rest do wonders for the body, mind, and spirit.
Until recently the collected medical knowledge didn't understand how much exercise a person should have and what exercises to do. Now with our computers able to gather the collective data from around the world we can see how exercise effects others so that we can now extrapolate that data and apply it. It was remarkable to find out that human beings didn't need overwhelming amounts of exercise but vigorous exercise that anyone in relatively good health can engage in. For example the simple act of walking can do wonders for ones' health and stamina. Yes, just walking, however the kind of walking and it's duration are important. One could do a brisk walk of 30 minutes several times a week and be in wonderful health. Walking briskly improves the circulation, works the lymphatic system and sharpens the mind. It flushes out toxins and firms the muscles and strengthens the bones. Why, some would say a brisk walk every day could add years of good health to a person.
Other exercise regimens from jogging to swimming and resistance training all have benefits. Dancing has become one of the most important exercise regimens ever providing the benefits of jogging, walking, calisthenics combined not to mention it's extremely fun to do and most can't stop until they're exhausted which is what good exercise should do.
Making exercise fun is the key. Doing it regularly as well as keeping a good diet and rest schedule can make all the difference in the world regarding a person's health. A low calorie diet, and of course always consulting a physician before you engage in any exercise regimen are essential but once you get started and see how enjoyable it is you'll find you'll be at it for a lifetime and gain the benefits quickly and long lasting.
Finally, don't think that exercise is going to hurt you. Being sedentary does more damage. You owe it to yourself, your family and friends to take that step towards good health.
