I have been sending out weekly training tips to members of my website and other people on my email list. If you would like to join the list and receive weekly emails, use the form at the bottom of this post.
This week's training tip is short and sweet.
The next time you work on a form and you come to a stepping movement, put the energy in your knees when you step.
If you think about it, most of the time you probably are just moving the leg, or stepping with the foot on movements such as "Stepping Three Steps" or "Whirling Upper Arms" (performed by stepping backward).
If you put your mind and your energy into the knee, and use the lifting of the knee as the focal point of your stepping, you will find that your steps will become more light and lively (as long as you don't stomp down as you land).
So don't lift the foot when you step, and don't lift the leg -- lift the knee. Think of having your "energy in the knee."
It will keep you from shuffling your feet, which is never a good thing, and it will make your steps more lively.
Also, when doing moving push hands or otherwise engaging with a partner to practice close-up fighting techniques and methods, the livelier you step, the more you can defend against foot sweeps or other disruptions of your structure if the opponent uses his legs and feet to try to unbalance you.
Let me know if you have any questions on any of the material the site or on the DVDs.
