Fitness fans or gymnasium users are always looking out to get the maximum out of their exercise programs. Knowing your target pulse rate can help in this endeavor. During physical exercise, the heartbeat rate goes up. As the intensity of the exercise increases, the pulse rate becomes faster. Due to this change in heart beat rate, the amount of oxygen and blood that gets supplied to the body cells get altered. Target pulse rate is understood to be the optimal state where the body is able to acclimatize to changes occurring due to physical power (which happens during an exercise schedule) well, and carry out the body functions most efficiently.
