PERIPHERAL HEART ACTION TRAINING: THE PRINCIPLE

PHA training alternates between muscles of extremities in the upper and lower body.For example, you start by doing an exercise for the lower body, like squats. Your circulatory system increases blood flow to those lower body working muscles in order to provide them with oxygen and nutrients.Then, you stop working the lower body and start doing upper body exercises, like push-ups. The circulatory system now has to move the blood flow to the upper body muscles. After a period of time, you stop and go back to lower body exercises, and then return to upper body exercises. Alternating between the two body halves forces your cardiovascular system to work harder as it keeps moving blood from one body part to the other.You will also reduce the build-up of lactic acid because as one half of your body is working, the other half rests. This lower build-up of lactic acid will help combat fatigue and allow you to train harder and longer.
