From swinging facing the platform. Make a very small set at the frontend and break just later than for a swing. Allow your legs to come forwards again and then sweep back again just before the peak so that you rise up vertically (as if standing up). Let go at the peak to step onto the platform and take the platform supports.When you are learning this trick, it is easy to bang your shins on the platform. You may consider wearing shin pads to protect yourself.
