When you make a point of being physically active, you are taking one of the best steps to improve your overall health. Your heart is first and foremost a muscle, and it needs regular cardio exercise to get and stay strong. Other benefits of exercise include increased ability to deal with the stresses and strains that go with everyday life. Since exercise releases endorphins, which are the body’s own "feel good" hormones, you will have a more positive outlook after undertaking any kind of physical activity. Making exercise a part of your regular routine is a great way to overall good health! Even setting aside 30 minutes per day to walk, climb stairs, or swim will do more good than you can imagine.
