The regular physical exercise is the first prop to improve his health from all the points of view. You are a man or woman, high or low, fat or thin, competitive or rather vague, his heart and all his organism will serve to him better if it does regular physical exercise. It helps to lose weight, diminishes the tension, and the physical force and the self-esteem increases. Also, it diminishes the cardiovascular disease risk.

The physical exercise strengthens his heart on having made it beat more loudly. His muscles increase also his aptitude to use oxygen, and oxygen is liberated more in them, what increases his aptitude to work. In the long run, the regular physical exercise does his most effective heart, and paradoxically, it is going to need to beat less times to work equally when you are in rest.

Another beneficial effect of the regular physical exercise is that the cholesterol HDL increases, of high thickness or "well", of protective effect on the arteries.

Nevertheless, not all the types of exercise are equal.
The one that improves the cardiovascular health is the aerobic exercise, or "exercise with oxygen": That one that makes to his body use extra oxygen and calories of continuous form. Cycling, swimming, walk or jogging increase the speed and respiration depth, warm the body and make to sweat.
The exercise anaeróbico, or intense exercise of short duration, like the weight lifting, can be also beneficial for the health, but it does very little in favor of the heart.
