The Cross Body Bookmark

The final line of connection in the internal arts we are going to look at in this group of articles is the cross body or spiral line. Many people consider the cross body connection to be key to the interesting body methods, load or force management techniques and movement dynamics of the internal arts.

 

At its most basic level the cross body connection allows us to actively utilize the opposite sides of the body in harmony with each other. If you think about someone walking naturally, swinging their arm forward as the opposite leg is forward, this is a classic example of this cross body connection in use. But this attribute of body motion and the associated tissues has a deeper reaching consequence for the internal artist.


We see the cross body used in almost every action the internal artist makes once they have achieved the spiral force so characteristic of the arts. Some styles talk of a crane and snake entwined or of two dragons coiling around each other, these esoteric visions or descriptions relate directly to the spiral nature of these arts and perhaps most closely with the spiral line. Without the cross body connections, the spiral is not formed.

 

In the anatomical model the spiral line refers to a specific group of tissues that wrap the body and legs, creating a type of corset or multi sided support. This lines use is demonstrated in the Tennis serve, the Cricket bowl or the ‘reverse’ punch of Karate.

 

The tissues of the Spiral Line are more complex in their association that other lines we have discussed but to briefly outline them. The line starts at the level of the first metatarsal bone in the foot, the bone we use to create alignment in many of the arts basic practices. Then through the ankle, running up the leg through the Tibialis Anterior and Peroneus Longus, via the knee joint we follow the line into the Biceps Femoris, the ITB and the Tensor Fascia Lata. Then on the back this line is related to the Erector Spinae and Rhomboids, but perhaps the most obvious appearance of the spiral is around the front of the body. Here via the Illiac crest the line follows the Abdominal obliques (internal and External) which form a X at the level of the lower Dan Tien. Then up from here the line runs in the Serratus Anterior terminating at the Occipital Ridge via the Spenius Capitus.

 

So this line runs from the first Metatarsal (the big toe foot bone) all the way to the back of the Skull and as it does so, specifically for the internal arts, it crosses over from one side of the body to the other. This is the formation of the body cross, a concept and physical reality that can be used to manage and project forces in a number of interesting ways.

 

Power of the twist

 

At a fundamental level the cross body method means that we can utilize a huge proportion of our torso muscle and connective tissue to generate large volumes of power. Some martial arts will avoid twisting forces in the torso, instead focusing on turning the pelvis. However this method will miss out on all of that elastic and potential energy that can be stored in our torso. We see the remarkable utilization of the spiral line in arts like Ba gua, where exponents will turn and twist creating huge volumes of power in short spaces and inside tight angles.

Here are some examples of the basic cross body method in use from around the world of martial arts.



 

Positional Security via not leaving your base

 

But there are some uses, many unique to the internal arts, that are also very interesting. One such use for this line is in how it allows the exponent to emit and receive huge volumes of power without ever leaving their stable base. This is achieved because incoming / outgoing forces are crossed over the body to the opposite side rather than leading the same arm and leg. The same side motion is used in some instances, especially in throwing, but it does mean that the practitioner may be lead out of their base or that their own power will make them commit to a direction. When we utilize the cross body or spiral connections the left forward leg will instead be linked to the right forward arm and the opposite on the other side. This spiral means that, rather than the hips being pulled in a straight line, the incoming forces is directed around them.

 

Power from the unity of opposites

 

In the later stages of training the spiral or cross body lines can be used in equal and opposite harmony. The practitioner may be closing in one side of the cross and opening in the other. Further, they may be spiraling down from right hand to left foot and up from right foot to left hand, all at the same time. This unique way of creating opposite spiral directions, again, keeps the exponents power within their base, but also creates a body that is extremely hard to control. Much like grabbing a turning wheel or a giant corkscrew the exponent will not be where they appear when the partner tries to grab, they will have moved already.

Next we need to look at how these major body lines work in harmony with each other to produce the unique ‘whole body power’ of the internal arts.

  • Addressing lower crossed Syndrome Articled 4 years ago
    The lower crossed syndrome is something that we see to a lesser or greater degree in new students. The lower cross is a term used to describe a specific pattern of muscular imbalance in the lower body which results in pelvic tilting and curvature of the lower back. If left unchecked, internal strength training where we are specifically working on the connective tissues and muscles in this area can actually compound postural problems, as well as increase the likelihood of injury under load. The lower Cross is characterized by a combination of both weakness and tightness in the lower torso. Specifically, tightness in the Thoraco lumbar extensors which is reflected in the hip flexors and weakness in the abdominals reflected in the Gluteals. This specific pattern of imbalance creates joint dysfunction at specific points along the lower spine and will cause the pelvis to tilt forward. Internal arts have specific training methodologies to address this issue. The corrections are achieved through 'releasing' the tightness in the thoracolumbar and hip flexors. We are aiming to bring the lower cross into a relaxed ...
