1, people stand on the chessboard, with their feet outside the figure of eight, their rear toes stepping in the middle of the tail of the back chessboard, and their front feet standing slightly in front of the middle of the chessboard.
2. When taking off, the back foot should land hard, and the wrist of the front foot should be hooked to drive the sand to jump up. At the same time, the hind feet should keep up, otherwise the tail of the board will be suppressed and the jump will not be high.
3. When jumping in the air, the front foot and ankle begin to turn backwards, and at the same time, the front foot presses in the direction of the board head. There is an action of crossing your front feet (that is, when you walk sideways, your front feet cross), while your back feet continue to lift. At the highest point in the air, the front shoulder is lower than the back shoulder, the center of gravity is pressed on the front foot, and then it lands smoothly.
