Regular exercise is an essential part of a healthy lifestyle.
It is natural for us to relax and rest whenever we have the opportunity, thus, a routine of exercise will help us discipline ourselves to get the exercise we need. During moderate exercise, such as brisk walking, the heart increases its rate and force of contraction in order to meet the blood flow needs of the exercising muscles. Thus exercise such as walking increases the strength and fitness of the muscles in the legs as well as the muscles in the heart. The blood flow to the heart is also increased during exercise. Most people with heart disease can, and should, have regular exercise.
