..you need to learn efficient way to lower barbell form overhead. Mainly to prevent injury  to any and every bodypart involved. 

The method I use differs from everything you read online on this subject.

Listen, Chinese weightlifters don't do it just to look cool. Panda pull really helps with technique, speed, and transfer of that speed technique  to actual lifts. 

I haven't seen any good online advice on teaching this movement, so please allow me to share my experience. 

Here is one particular combination that I like for fixing this problem.

As a weightlifter you should strive to achieve good level of endurance  early in the winter preparatory phase (far away from major competition,) and maintain it throughout the year. Higher level of endurance might (indirectly) improve your results on the platform.

It’s great to observe good technicians in three dimensions (and not just YouTube,) so your eye can develop, and you could spot imperfections   when you’re coaching. Problem is, that by observing elite you never learn  how they got to that level.

Learn simpler and better alternative  to a popular snatch balance exercise. Alternative that will actually teach you to control the barbell and lift more kilos.
