It becomes easy that if you are very soft and mobile in your body, you are drawn to exercise that suits/is easiest for the body to perform, as a mobile/soft person likes to do yoga. The slightly stiffer and more stable person prefers to do slightly heavier strength training, etc.
This test aims to determine which body type you are and which hormones/hormone-producing glands are dominant in you. The doctrine of the different body types is based on Dr Elliot D Abravanel's research. With the right training, you can help create a balance between the different hormones (just like food, sleep, etc.). Depending on which hormones are a little more dominant in you, you have certain characteristic signs and traits.
