Repulse Monkey is one of the key moves for the Sun form.
It is important to remember that it is a travelling form so you move from north through south whilst turning to the west, then the east, then the west and finally back to the east.
Initially students do not remember that it is a travelling form and end up trying to do it on the same spot which results with them tangling themselves up.
This is a summary of the form below.
I hope you enjoy practicing this form and that you progress well with your Tai Chi studies. Remember Kai Zen - small steps to progress forward.
