I trained for over ten years on the balls of my feet. Spent some time training more flat and transitioned to that.

General rule in my opinion is balance. The Thais generally kick these days with the base leg relatively straight (therefor they are more balanced) underneath the body. Westeners often fall when the leg is caught just cause they kick in such an off balanced manner. At least thats my limited experience and observation.

Leg kicks can be a bit different... but the general rule in my opinion is balance at all times.

Certainly a good coach watching you would be the best in my opinion.

Seriously though its not rockey science. Watch some good kickers and just look at what they are doing and copy it. Done!

We over analyze everything in the west it seems to me. Over think it (left brain). We are also conditioned to look to the teacher too much and don't know how to refer to self.

What angle the leg? Do both and see how it feels for you. Watch fighters who you think have good kicks and see what they do and then try it out and see if it works for you.

A student asked me a question the other day. Thjis way or that way. I told her to try both and see how it felt. She came up with what I would have told her.

Another thing I find helps people a lot! Stop, relax, get into a space where you pretend you already know it. Really pretend you know what you are doing... then do it. Let go and just play.

School and parents have taught us to gwet it right and its "is it right or wrong?" Just fucking do it and keep getting better. its a journey that can be never ending (if you want to move towards your potential)...

Teacher tell me, parent tell me, doctor tell me, priest tell me, government tell me...

My goal is that I'm a guide, not a teacher and I guide my guys to start to feel there body so they can know what they are doing and feel what works for them. And of figure it out...

Get into right brain a little more than just left. Both balanced is ideal. We have a tendency in the west to be mostly in the left.

Diamond Gate (exercise to link left and right hemispheres before or after training - also helps reset nervous system, amazing!!!!!!! for recovery, and even helps line up your jaw - which affects neck and back etc)

Alternate Nostril Breathing - linking left and right hemispheres

Also try just oxygenating right brain - plug right nostril and breath deep and slow through left for a minute or two.

Balance is key but it could be worth doing just right brain and seeing how you feel training - maybe compare with just left....
