What will happen to the heart without exercise?

Answer 1

when you don't exercise your heart starts to collect fat, your heart's arteries start to get stuffed with fat and in result it make it harder for your heart to send blood around your body. Sometimes (well most of the times) when that happens you usually end up of having diseases such as heart attack and so on. Better be careful.

Answer 2

If you mean when you stop, you lose blood volume, lose capillary density, heart strength and muscularity will begin to decrease. Blood vessel plasticity decreases. Many other processes occur which take you to a lower baseline which is natural since your body is always seeking its lowest energy state. When you exercise you force yourself to "get fit" which uses energy yet evolutionarily speaking, this is not good since more fit people burn more calories and calories may not be available for consumption.

Answer 3

your heart needs exercise to keep healthy. With out exercise your heart will lose fitness and have to work harder to pump the blood around your body. Later in life this can cause strokes and heart attacks.

Answer 4

you will die
