Palm attacks are one of those techniques that I just can't seem to improve. Anyone got some advice as to how it should be done?
The two different ways have already been outlined. Palm heel vs. entire palm.
I'm interested in the nitty gritty details: how you practice the palm strike, and how you use it, for sparring, self-defense, or even board breaks.
The two ways I practice are in the air and on a heavy bag, single and double strikes. My arm position is similar to a punch, from the waist, extend it out palm down and a couple inches from the target I turn the fingers up.
Use in sparring is difficult because of the gloves. A MMA glove or wristwrap glove would allow you to that strike but there isn't a lot of padding in the middle so use caution.
Self-defense wise it's nice because you don't tear up the hand as much as when you hit with a punch. The structure of the hand seems to absorb striking a hard surface better. The palm heel is the classic jam the nose into the brain, instant kill, women's self-defense move.
Palm strike is the required break for a couple of our
lower belt tests.
If you like, feel free to also discuss when you would use one or why.
This is a good all around strike. I use it when hitting to the body, it works best for that. I have also seen spinning techniques to the face that look effective.
When you say you want to make your palm strike powerful like a punch what do you mean? Speed with the arm? When it hits a target?
When you are hitting a target remember that the power dissipates really quickly. It hits and the target absorbs it, that is why palms generally don't bruise but they hurt like hell. Punches hit with about a quarter size target, depending on which knuckles you hit with. Regardless, even if you hit with all four knuckles the surface areas are very different with the palm being much larger.
Finally look at the structure of the strike. With a punch the wrist is aligned with the fist. Your arm absorbs the impact. A palm doesn't have a lot of support up near the fingers so when you the target it can bend the wrist back. The wrists need to be stronger than with the punch, IMO.
