Tim,

For the last couple of years, I have been working at realizing the "feeling" of true balance. This is, of course, a prerequisite for utilizing natural, whole-body power and developing the so-called ward-off energy, or Peng Jing.

I have been paying special attention to the concept of Song (relax/sink) and aligning my skeletal frame correctly so that I may access the elastic quality of the connective tissues as my primary source of power. Also, I have been learning to move from my center of gravity, the pelvic area, or Dan Tian.

My question is, how can all of this be applied to moving on the ground? I have been experimenting with the 'upa' and 'shrimping' drills of BJJ, but I feel like I am using "brute force" to accomplish the movements. I cannot use most of the images that have helped me make progress in my standing practices, such as lifting the crown, maintaining vertical alignment of the hips and shoulders, letting the weight fall through the feet, etc.

Could you give some basic guidelines for aligning with gravity, while in the postures used for groundfighting?

Sincerely,
Steven

On the ground, the same basic guidelines for alignment remain unchanged (lift from the crown, elongate the spine...). The body should also move as a coordinated unit. The base is any part of the body that is in contact with the ground. When standing, the weight falls through the feet. On the ground, it can be just about any part of the body, and the surface area of the base is usually larger, but the same principles apply. In general, on the ground, you try to either spread your weight over as great an area as possible (for stability) or focus your entire body weight into a small area (to put pressure on the opponent). Movement of the hips and center is primary, just like stand up.

Tim,

That makes sense, but what about falling and rolling? Are there any special guidelines that apply when the back is rounded?

Also, does the center of gravity remain located in the pelvic area?

Thanks,
Steven

When falling, the same principle applies. The way to break a fall is to distribute the shock of impact along as great a surface area as possible (primarily soft tissue). When you round your back to roll, the principle of elongating rather than compressing the spine still applies. Same for arching the back.
