Segmental body composition analysis is ideal for enhancing your sports performance. It will allow you to identify any physiological & biomechanical asymmetries so that you can tailor your training & fitness regime to improve the distribution of fat & muscle mass & achieve your personal goals. To use, place your feet over the four footplates on the platform & gently pull the hand electrodes on the sides of the platform.
