 The rider of a snakeboard stands with one foot on each footplate (the feet are usually fixed to the board using bindings) and, by moving his/her feet in and out in conjunction with the shoulders and hips, is able to propel the board in any direction using only body weight.This transfer of energy is called nonholonomic locomotion.The board moves in a motion similar to that of a snake—hence the sport's original name of snakeboarding.
