At first the board is placed on his stomach. It is narrow, 8 cm, five girls are supposed to stand on it, which amounts to over 250 kilos. t's as if a car with very narrow wheels that weighs a ton drove over you. Did he make it? After that 5 girls walk on a shelf board in classic trampling fashion. It is an easier task. At first the board lies lengthwise and then sideways. Then another friend lies under it.....but he is less resilient. Time:8,17 min.
