Hi,
If I had a scanner I could send you some pictures along with the exercises. This is an exercise that is mainly used for hand power and strength.
The stone lock is a very common training aid in the chinese martial arts, especially in the southern styles which emphasize hand techniques. A stone lock (Shyr Suoo) is a stone shaped like a chinese lock usually weighing from 30 to 60 pounds. The stone lock is generally used to train catching speed, strength and the coordination, wrist and arm. The practitioner swings the lock, throws it up in the air so that it spins and then catches it by the handle. There are many training techniques, but since stone locks are not readily available in the Western world, teachers are not inclined to show these exercises.
However, even without a stone lock, you can still use the same principles with a brick to train your grabbing and catching speed and power. In brick grabbing training, use a brick which weighs about 20 pounds, and whose width is apprpriate to your grip. There are several methods of training:
DROP GRABBING:
Drop grabbing is the easiest way to train with a brick. Stand in a horse stance and hold the brick in front of you. Lift the brick and then drop it, catching the brick with both hands before it hits the ground. When you are used to the weight, use a heavier brick, uo to 50 pounds or more.
I have a few more but I will be able to send these tomorrow, I will try to get my hands on a scanner to send you the rest. There is also the Staff and Swinging Weight Training which I will tell you more aboutr tomorrow.
I certainly hope that this information is useful.
Have a great day
Pierre
