Exercise to help maintain a healthy blood pressure level. People with high blood pressure are generally advised to do aerobic exercise (such as cycling or brisk walking) and strength training with light weights. If you have high blood pressure, check with your doctor before beginning any exercise program. Be careful if you lift heavy weights or do isometric exercise—such as pushing against a wall or pressing palms together to build strength. Keep the intensity light to moderate, and rest between the brief bouts.
