How is exercise good for the heart if overworking the heart is bad?

bombastic asked:


Experts say that exercise is great for the heart. On the other hand, they also say that when people are overweight, have high blood pressure or diabetes their heart works too hard. Then how is it that exercising and making your heart work hard a good thing? Can someone explain this contradiction?

    It strenghthens the heart muscle, conditions the heart, and lowers heart rate over all, reduces weight which reduces work load of the heart.

    Think about it - Exercise is done for a short period of time; it is during this period that the heart conditions itself by becoming more efficient and powerful. In the time afterwards, the heart slows down to its normal rate and becomes slower to “rest” at night.

    When someone is overweight, however, the heart is in an exercised condition all the time, with no rest during the night or day, remember, the heart can withstand great levels of stress, but not for any prolonged period of time, like several months or years. Eventually the heart will weaken, as with any organ that is overstressed, and enlarge to try and become more efficient. This enlargement is not better for the body and eventually causes more severe heart failure.

    In a healthy person with no cardiocascular disease of any form sprinting is VERY good, far superior to walking for your heart and hormonal systems.

    There is no animal in nature that does “aerobic” activity . None of them jog for 30-60 minutes with no rest

    This is very unnatural. On/Off is the way to excercise.

    Intermittent walking with random sprints . NEVER jog for 30-60 minutes

    NEVER do the intensity between a sprint and a walk. for a prolonged time with no rest.
