I got interested in lv carnies chi gung book, laughed, send sensations into your partner never experienced. And practical like pick up a guitar and hit the accidental right note stuff is all good. Mantek chia's exercises in his books, 2 chairs apart, with ur body between the ends, i haven't worked on, but good use of chi.
At simpliest, u could focus left to right hand, and repeat. Or focus on a body circuit, like left right eye, chi gung 20/20 vision training is a good exercise. Chi gung has been mentioned to come from a dynasty that formed a lot of martial arts.
An elderly man on youtube, could knock over a brick from a distance with chi, fake dunno. A documentary recently on chi gung monks, bend crow bars on their head. From my experience I think chi travels faster at a distance, and is easier to send. Although no proof of anything.
Once ur good at chi gung, live the life and that, maybe u can jump 10 feet in the air, cause an attacker internal body failure from a distance, I do a circuit, but I very rarely do that. The harmonizing the dragon tiger classic, says to do lots of stuff seasonally to get the most benefit. I might get into it one day, its a nice belief system, and also says to die at 100 is young to die. Sounded good.
