YUDAIGONG (THE EXERICES OF THE ARMS)
At the beginning of training stand under a tree which one can just get one's arms around bend knees lightly and squat down, then hold the tree tightly in two arms with two middle fingers buckled and pull up the tree. this kind of training should be practised several times a day and spare no effort.
through two years of this training, the strength of the arms, the waist and the legs would be obviously increased. for example if you hold a tree trunk in two arms with slight shake, the tree trunk will be tottering and the branches and leaves of the tree will fall down.
for the next step have a training of holing a stone drum in two arms. because the stone is very glossy, so it is very difficult to hold. only after a long practise a good result can be gained. through five years of such training one can hold a stone drum of 500kg in two arms and walk nimbly. the exercise plays an important role in shaolin wushu. for instance during the fighting against the heavy odds you can use this kung fu to hold two or three enemies in your arms and let them bump against each other. finally they will be seriously injured. this an indispensable kung fu and shaolin monks practise it very often.
