I have an image in my mind of how I want things to look (it IS subject to change). In the sand, the left leg will ALWAYS be catching the pole. I'll put up film from the clinic I did with altius this past summer if you'd all like... We're doing exactly what I'm doing in the vid (although people aren't taking off as flat).
You can think your doing it right all you want but as soon as you take off the ground your hips swing into the pole, the only thing that stops them is you catch your leg. You are holding two high for your ability and as a result somtimes you dont even have a free take off in the sand. The goal may be to hold high but if you cant do the drill right first with a lower grip you are doing nothing for your self by raising it. In in a trap of thinking your doing it right because you are catching your leg on the pole like altius said you should. But look at this vidio of Isinbayeva doing it the right way. Notice she drives her chest at take off and makes a consious effort to hold her hips and trail leg back the pole almost reches verticle before her leg finally catches on the pole, you simple swing your hips off the ground into the pole and say your holding your hips back, your not holding them back the pole is. Here is Isinbayeva video and your video, because the leg catches they me look simuler to you but they are nothing like each other. (Also her leg bearly taps the pole not really even catching on it, your collides with it.)

Next time you practice lead with your chest into the take off, feel the stretch of the backwards c and hold that position as long as you can once your hips get there let them catch on the pole, dont swing them into the pole defeating the purpose of the drill.
