Steps

• Run at a wall at a nice steady pace. As you approach, your weight will fall backwards.
• At the same time kick up one leg to clear the height of the wall. The trailing leg will then be powered through.
• Place your hands on either side of the legs and to keep the momentum going with a push away from the wall.
• The momentum here will fire you over the wall. While in the air your body weight will be brought forward to prepare for landing.
• With your body weight moving forward, you should begin to straighten up and get your feet ready for a nice landing.
