How does exercise affect blood pressure?

A 2023 analysis of nearly 300 randomized trials found that several types of exercise were effective in lowering resting blood pressure. Exercise types included aerobic exercise, high-intensity interval training, dynamic resistance training, isometric exercise training, and combined training (aerobic exercise plus one of the other types of exercise). People who are over age 50 and have not been exercising much should check with a doctor before beginning a regular exercise program, since some types of exercise may not be right for them.
