The “teeterboard,” or, Korean plank, resembles a seesaw. They are usually 9 feet in length and the board is divided in the middle by a fulcrum made of welded steel. A square padded area is at the ends of the board where the performers stand. Watch David James Rimmer and Stéphane Beauregard training on the teeterboard. David has been practicing men’s artistic gymnastics for 13 years and has been trampolining for 4 years. He currently is working for Cirque Du Soleil on the teeterboard.
