I have tried some physical conditioning for iron palm, but I have a preference to the energy development side of it. My personal preference is that, while many do advocate physical conditioning, you’re taking a big chance because of the risk of nerve/muscle/bone damage. They say that there was bone breaking done in olden times to strengthen the hands for iron palm and the other bones for iron shirt/etc. and that’s just insane to me. I’m also biased to energetic development because of how fast I developed.
What I’ve found is that if you’re naturally strong enough energetically, physical conditioning for iron palm/shirt becomes more and more meaningless.
Also, I had a nervo-musclular injury a few years ago and I got into reiki, so I had put in a lot of effort/energy into making my hands/wrists well. For anyone interested in iron palm/shirt, becoming attuned in reiki is a big help given how strong the energy is.
I’ve seen some people giving pointers on punches, where they say your arm should be relaxed, which is fine, but then, they say that when you’re about to make contact, to add some more tension in your muscles, such as the fist. And they don’t make the distinction that it’s just for learning the movements and then, you use less and less tension, as you go on.
Take a lesson from the drunk driver survivors of the world. When they are drunk enough, their muscles don’t get tense when they crash their cars. Like flowing water, they will surround their steering wheel and bounce back. When they get out, they have only a minor injury a lot of the time.
The more self-control you can exert on your body, especially on the wrist/hand areas, the more you can relax the soft tissue. This will make your bones and soft tissue" wrap around itself".
For a finger strike with all four fingers together, it takes very little energy and they shouldn’t be tight together…just lightly touching, but pretty much no space in-between the digits. The thumb can hang loosely by the side and out a little. For a 2 finger strike, the pads of the ring and pinkie finger don’t have to touch the palm. It’s enough to just have the fingers bent at the middle knuckle, so the tips of those 2 fingers are pointing back at you. Again, the fingers are only lightly touching.
For the thumb in the 4 and 2 finger strikes and the ring and pinkie in the 2 finger strike, keeping the thumb and the ring and pinkie fingers loose will let them “wrap around” anything that happens to run into it. The compression of the soft tissue of the ligaments and muscles and skin will happen and then, rebound.
For palm strikes, it’s the same thing. The wrist is bent back, but there is little tension in the muscles…just enough to keep the wrist bent. Most of the muscles of the hand can be kept very loose. The fingers are slightly bent with only enough tension to bend the digits, so the ifngers and the other parts of your hand can wrap around anything they run into to the limit damage.
Now, when I had my nervo-muscular injury, I found no diminishing of any of my reiki abilities. The constant practice helped me increase my skill. The hand itself has a large number of energy points, which is one of the reasons why hands can be more naturally sensitive to energy than the forearm. The hands are one of the areas that are used in skin-to-skin contact sensuality. Most of the body parts are good, but hands are often favored by many. Body massages, especially back rubs, are so good, not just because of decreasing muscle tension and increasing ‘good feeling’ chemicals in the body, but also because the back is filled with tons of energy points. Because the hands often do a lot of work in someone’s life, energy exchange is done quite a lot in the hands. When the hands are used on the back, there is energy transfer to the energy points in the back. The signals and energy are sent to the brain, which is able to use more energy on the material and nonmaterial levels because the body knows what it wants. It knows what’s wrong and knows how to fix it. The body senses the energy nearby and absorbs it from the hands, though it can take from any part of the other person’s body. It’s just that the hands are closest and are already in contact with the energy points.
But, even if you were you screw up the hand on a material level, it won’t stop you from implanting energy from yourself into someone else for healing or anything else, good or bad. Instead of visualizing the energy coming out of your hands, you can think it is coming out of your nostrils or your knee cap.
The same ability to direct energy out of yourself can let you direct it out of someone else from a distance. I’m not talking about any empty force work. That’s pushing. I’m speaking about sending someone’s energy out of them to make them winded or even unconscious or dead. It can happen, but it depends on your skill level (how much you can move at one time in any given second – similar the empty force, but the technique is different and requires less skill to perform on a regular basis). Another part of the energy development track is increasing your skill in removing the energy of solid objects, making them more brittle and easier to destroy. This will cause less damage to your material body parts and make you look like a destruction God. How far you go is limited to you. The same energy in you is what’s in inorganic materials. Humans are biochemical machines, which use both organic and inorganic pieces for survival. Giving healing energy strengthens the overall energy field of the creature. The reverse is just sapping it away, though I have never heard of any dim mak lessons that even touch on this, while talking mainly about using chi on the meridians. The same chi that helps keep the atoms of your body together, helps to keep the atoms of a piece of stone together. The more you take, the more brittle it becomes, though I’d advise against drawing it into yourself. The Earth is a good place, unless it’s a life or death situation and you need a “recharge”. A good cleansing is recommended with that. Bathing in epsom salts, showering, etc. As a naturally empathic person, taking in someone else’s vibrations isn’t pleasant. It’s often down right disturbing.
Edit: Just for completeness sake, if you’re gonna recharge, recharge the dan tien. Don’t just have it floating around your body. Visualize it going into your subnaval dan tien, like you would with energy raising exercises. There’s such a huge focus on the subnaval dan tien for charging in Tai Chi that you should just use the familiarity you’ve developed in your practicing. This familiarity will let you do more reflexive energy work than thinking ‘all right, it’s floating in my arm, now I gotta move it to my right leg to block this kick to my knee’ and you can get back to working on saving your life.
Edit 2: Forgot. If you want to ignore ‘energy sapping’ go with energy changing. Imagine that someone/something’s energy level is not regular, but just very very weak. So weak that you can easily and effortlessly break through it. You could call this the opposite of a ‘dragonball power flare up’, if you wanted to use a visual from manga. But, bare in mind, I haven’t used this technique in a fight. It’s only theory at this point. I came up with the idea based on the fact that one day I was feeling sluggish when I woke up. Then, I imagined my ‘aura’ was super powerful and I instantly perked up and was back to my full of energy self all day long and had a very keen focus. If you were to practice this, just imagine that the energy of the aura has gone down, like when you turn down the strength of a fire and you shouldn’t worry about ‘well, where is the energy going’. The important thing to think about is that the energy is so very low. Think of it as a variation of using 4 ounces to move a thousand pounds.
