Forearm Score
Begin standing against a wall. Feel your body pressed to the vertical surface. Feel your forearms touch this plane. Choose one forearm. Slide to the floor without letting this forearm lose contact with the wall. Once at the floor, cross the room while measuring your path using the forearm of one or both arms. At least one forearm must stay connected to your path at all times. End when you reach your starting position mirrored on the opposite wall.
