Dynamic exercise activities keep joints and muscles moving. Examples are swimming, walking, cross country skiing, bicycling, weight training, and house cleaning. Blood circulation, strength, and endurance are improved by these continuous movements. Static exercise, also known as isometrics, exerts muscles at high intensities without movement of the joints. Pushing on a heavy couch that does not move is an example of static exercise.
Static exercise improves strength, but it also drives up blood pressure in an instant.
People with circulation problems and high blood pressure should avoid exerting pressure without muscle movement. If you perform static exercise, never hold your breath. This can drive blood pressure dangerously high. Stretching exercises may be dynamic or static. How they are performed determines this.
