Currently I am writing my first book on completion with body and I was searching for technique to transform the muscle memory. The search ended when I found a discourse by my Guru, Paramahamsa Nithyananda (fondly known as Swamiji) gave when he was expounding on Patanjali Yoga Sutras.
What is muscle memory?
Muscle-memory is that part in you which makes the decision to do any act spontaneously, and executes it within micro-milliseconds – even before you become aware of it! Swamiji explained that muscle-memory means your everyday actions and reactions. Your actions directly impact your muscles memory. Anything you do consciously again and again directly strengthens your muscles. So the more you age, the stronger you should become! That means you should become stronger and more intelligent as you age. The paradox is this is not happening because of the negative practice we create over time which strengthens the unconscious ideas in our inner space and weakens us. If you understand the science of practice (abhyasa), you will be stronger every moment and your muscles will be very strong!
