The most effective exercise in reducing blood pressure is the "wall sit" This involves sitting in the air, with the knees bent at 90 degrees, while resting the back against a wall. Just 8 minutes of isometric exercise, three times a week, can lead to a significant reduction in blood pressure.
Isometric exercises work by temporarily reducing blood flow to the contracting muscles. When the contraction is released, blood flow through the muscle tissue increases, which causes the blood vessels to relax more and creates less resistance to blood flow.
