Hi johnnyboyleeds, thanks for the advice man. Believe it or not, I have actually been practicing those sorts of things with my clients and students wherever possible. i believe that my main sticking point is going to be opening, and dealing with approach anxiety.
my degree was in psychology and have a background in NLP as well so I have a basic grounding in body language, kino etc. Like you said though, there will always be a degree of hesitancy when it comes to my clients... I am SUPPOSED to remain professional... although breaking rules can be fun!
Btw, my background is in judo, bjj and some mma
