Because I seem to be developing a reputation here as a curmudgeon (ok azzhole) I want to share a bit. This is not Gao style proper but more Bruce Frantzis stuff. Same thing, different method.
In my opinion the first thing a beginning student needs to learn is how to move the body as a complete unit. This is done by focusing on using the hips to move the body. Now realize this is waigong. Most styles have this. Some nanquan styles like WC, SPM, WE, etc concentrate only on the waist I think.
Anyway, BKs method is to use a neigong training method. Gao style uses the tiangong I mentioned earlier.
If you stand in neutral stance about shoulder width and shift your weight very slowly side to side, you will yourself moving from your upper body if you are a beginner. Concentrate in relaxing your body weight downward and move only from your hips. Imagine a rectangle from the fold of your shoulders to the fold of your hips. Keep, very religiously, this rectangle perfectly level. Get a friend to check it. If you think you are doing it right in the beginning, I assure you you are not. Get someone to put their hands on your shoulders and hips and see. When you can move the whole body, centered around the hips, all at once simply side to side, you are doing neigong. This is not the only way or even the quickest way of getting it. You can also just change bow step to bow step smoothly. But I recommend it. Remember this is only the very beginning. OK enough typing. If you have questions I will do my best. If you don't then that's it. If you were here it would take you a good while before you could do this to my (or your) satisfaction.
Good practicing,
Buddy
