Fitness helps to lower blood pressure. Aerobic exercise and resistance exercise can effectively improve blood pressure, control blood sugar and improve cardiopulmonary endurance, while resistance exercise can increase muscle strength. After all different types of exercise, resting systolic blood pressure and diastolic blood pressure decreased significantly. However, after isometric exercise training, systolic blood pressure and diastolic blood pressure decreased the most, reaching 8.24/4mmHg. Followed by joint training, blood pressure decreased by 6.04/2.54 mmhg；; After dynamic resistance training, aerobic training and HIIT training, blood pressure decreased by 4.55/3.04mmHg, 4.49/2.53mmHg and 4.08/2.50mmHg respectively.
