Working out for 30 minutes a day can improve your overall cardiovascular health, and it is especially useful for lowering blood pressure. Even light exercise like walking can make a big difference in decreasing hypertension. When you do cardio exercise regularly, your heart does not need to use as much effort to pump blood. Over time, you will need to increase the strenuousness of your workout to achieve the same heart rate. If you feel like you don't have the time or energy to go to the gym, try taking a brisk walk at lunchtime or using the stairs at work. Some activity is better than none.
