Re: Ki energy defined
To be fair to the "non-muscular" guys, practitioners who have the juice consistently produce results which are asymmetrical to the amount of effort they put into their techniques. Even after seeing and feeling it for years, I am still amazed by just how effective the initiated can be while putting very little energy into the system.
I just like to razz the anti-resistance training and "non-muscular" guys because they are still dependant upon their musculature and gravity for all of their own force/power/work, no matter how deep down the rabbit hole they go. Since you are still dependant upon your musculature, you might as well have one that is high-functioning. A lot of serious health problems loom in the future of those who forego moving around heavy things.
