How to improve hip flexability for the round kick?

[SteffiCurdy]

I would also add that the standing foot has a lot to do with a well executed round kick.

You have to twist your standing foot! trying to do a head height round kick with you foot planted forward means you are jamming your hip bone in the socket!

At the point in which the round kick should strike your standing foot should be facing almost the other direction away from you. This means you hips are in a far more natural position and this improves the height and power.

Great
