Strengthening and Conditioning the Charp-Chui
Well there are Charp Chui push-ups and there are Charp Chui push-ups.
Buksing_king are you doing your Charp-Chui push-ups right directly on the knuckles? If so, there maybe some things you need to consider about the natural angle of the Charp-Chui position of the hand.
There are three hinge joints (knuckles) in the fingers, with the exception of the thumb which has two. The main ones used for most striking techniques are the MCP (Metacarpophalangeal) joints. Those are the ones at the top of your plain old fist. The next set are called the PIP (Proximal interphalangeal) joints, the ones you use for Charp-Chui. Consequently the “distal” knuckles are called the DIP joint.
First off, most hands in the Charp-Chui position has the third digit (middle finger knuckle) taking most of the pressure in this flexed position. Unless you are a rare breed that can have all of your PIP joints evenly aligned, which in such a case, the pressure (wether in push-ups or striking an object) can be more evenly distributed. But I’ll assume that your hand is more the norm. So if you are doing push-ups directly on the PIP joints, then more than likely it is your third digit PIP joint taking most of the pressure, which inadvertently will not benefit the rest of the other PIP joints (knuckles), unless you are varying the angles of your Charp-Chui to give equal attention to the rest of the knuckles/hand, as was mentioned earlier in one of the posts. If not, and you are doing them directly on the PIP joint, inwhich your middle knuckle is taking the brunt of it, which would not be beneficial and would more than likely be too much stress on the joint/hand in that position.
One way to consider doing Charp-Chui push-ups and conditioning them, is to perform them with the pressure distributed on the phalangeals “between” the PIP and the DIP joints. This can be done (Yueng charp position) by slighlty bending your elbows about 45 degrees toward your body (depending how far apart you are spreading your hands in the push-up position) so that the pressure will be distriduted on the flat surface of the fingers between the PIP and DIP joint. In this way you can focus strengthening the fingers, the metacarpals (back of the hand), and the wrist. Again, the third joint will be taking most of the pressure, but at least in this position more pressure will be distributed among the other fingers of the hand. So I would suggest variations of the hand position to increase attention to the other fingers, as long as the wrist position is able to maintain a safe and straight alignment.
Now concerning the preference of striking objects vs doing push-ups, I beleive both are good as long as they are done within reason. For those suggestions made in an earlier post that mentioned striking a sand bag rather than push-ups, indicated to me that that was supposed to be “safer” is up to personal discretion on this matter. This depends how hard one is striking a sand bag, because if you are striking a sand bag with whatever amount of brute force one may apply, this can actually be worse than doing push-ups. Strike a bag full of sand and you will know…it is hard! With push-ups in the proper position, force can be slowly increased per students tolerance level with reduced risk of injury. (i.e. in standing against the wall, on the floor hinging on the knees, etc…)
Now it has to be remembered though, the emphasis of the Charp-Chui is to have the advantage of creating the greatest amount of damage to soft tissue area, and other vulnerable areas where large bone and muscle mass are not in the way. So slamming into heavy sand bags (or other heavy objects) using the Charp-Chui is not really necessary and often times can cause more damage than good to yourself. Granted, it would be a great feat to slam with a Charp-Chui into a heavy object as hard as one could with a plain old fist or an open palm, but that is not genrally the rule in this case.
It’s good to train hard, but train smart…
