Cardiovascular exercise does contribute to heart health and reduces the risk of high blood pressure. Walking, running, lifting weights and natural exercise from physical labor are among the best aerobic exercises for heart health, according to WebMD.
Aerobic exercise is good for low blood pressure because a strong heart works more efficiently, according to Mayo Clinic. Some people lower their blood pressure enough through diet and regular exercise that they are able to mitigate the need to take blood pressure medication. Thirty minutes of aerobic activity daily is optimal for heart health. Visit a doctor for a physical examination before beginning an exercise program, especially if health concerns such as high blood pressure exists.
