With a regular workout program, your resting heart rate (RHR) is likely to decrease over time. This occurs because consistent exercise improves cardiovascular efficiency, allowing your heart to pump more blood with each beat, thus requiring fewer beats per minute at rest. As your heart becomes stronger and more efficient, your overall fitness level improves, contributing to a lower RHR. Additionally, regular physical activity can enhance autonomic nervous system function, further supporting a healthier heart rate.
cardiovascular fitness deals with the heart. if you don't take care of it, chances of heart attack increase. cardiovascular fitness is one of the most important things in fitness. this will decide how long/how well you heart can support you.

Potassium levels DECREASE heart rate, and maybe lead to severe cardiac arrest.and for sure, this is a mechanism of how potassium level in ECF can decrease heart rate:first, the potassium level increase in ECF making its efflux increase, due to activation of potassium channels in pacemaker cells, then the slope of pacemaker action potential will decrease, which means that the duration of one beat is prolonged, and this lead to decrease the numbers of beats in one minute, which by turn means that the heart rate is decreased.
It improves your stamina, because if you run regularly your body will get used to it, so you can run on and on for longer, helps to keep you fit too, eating healthy also helps.
