Exercise's Effects on the Human Body

Regular exercise offers many positive benefits that will keep you living independently and reduce your risks of getting certain diseases and injuries. Although gyms and fitness boot camps are places where people typically exercise, you can strengthen your body by taking long hikes or walks, dancing a few hours of salsa or playing your favorite sport. You'd be having so much fun that you'd forget the benefits that exercise gives you.
All forms of exercise improve the heart rate, blood flow and general heart health. Average, healthy adults have a heart rate of 60 to 80 beats per minute at rest. Moderate-intensity or high-intensity exercise will strengthen your heart, allowing it to pump more blood into your body, which can reduce the resting heart rate to 28 to 40 beats per minute, as in most elite endurance athletes. As your heart gets stronger, the stroke volume also increases, which is the amount of blood ejected per beat from the left ventricle of the heart. When the left ventricle is filled up with more blood, it is stretched further, which causes an elastic recoil to pump more blood out. Like skeletal muscles, the heart's size also increases as it adapts to exercise.
