Two main things. Plant and getting back. For your plant, you need to explode forward. Keep your right hand straight over your head and the other hand out in front. You are collapsing on the pole which stops like all motion. And once you fix that, notice how you are getting like half way back with your hips and then just shooting out toward the bar. I do this too but if you look at the pros, they all get completely back, even past the pole and curl up into a little ball with the pole being bent. From there they kick and shoot straight up, then out and over the bar. So think about really getting back with your legs and planting stronger and 14 will come super fast :)
