Just a few tips from Ken to help your Wing Chun improve. Don't be greedy with the hits. Often people are already hit without realizing it. You don't always have to strike high. This exposes you to low hits.
Many people have no rooting.
The stance is weak, not sunken. The knees should be in. You should feel like you are melting into the ground. You can practice for a lifetime but if your stance is poor you will have wasted all of your effort. If you meet the right Wing Chun guy, you will be in big trouble.
