As a vault coach, I can't see myself advocating the pole push. Some boxes have little lips and there's a disaster waiting to happen. High school runways are just not that perfectly level either. Also, I get the free arm pumping thing, but now the other arm is awkwardly held and all your focus is on keeping the buttplug centered, isn't it? I would love to read an article by the coach that teaches this.
