wow, i so did that like all last year!!! Do you kinda do a tuck and shoot, or do your legs just spread apart and flail away as you pull up the pole? I did both
but i don't have that problem anymore...all i can say is that i did a lot of repetition, maybe you should try moving to a smaller run like 4 lefts and with a low hand grip, work on turning over a bungee cord that is not too low, but high enough for you to just barely clear.
Just focus on getting the feet together to the top of the pole and then cross over the ankles to initiate a turn and you should be set, try squeezing your butt muscles when you invert, thats what people told me when i would kick...hope this helps
