You must think, ponder, and analyze, this is a very good thing. I encourage all Wing Chun students not to just do things by rote or because someone tells them, but to genuinely consider what it is they are attempting to achieve. Whether or not you understand everything correctly at first is not so important. The intention is what counts, and what will carry you forward in the development of your martial art.

If you’re like most, you’re going to stagger into the change-room change out,get in your car and grab a quick burger, pizza, or some quick fix.  When it comes to getting fit/healthy/buff/ripped/sexy/etc, your workouts are only half the equation.  The other half of the equation is Workout Recovery and what you eat.  And because I love you guys so darn much, here are my top Post-Workout Recovery Techniques.

About Wing Chun Kung Fu
Generally, everyone knows learning a martial art helps to improve your physical fitness, develop discipline and gain knowledge of self-defense. However, the main purpose of practicing Wing Chun is to learn practical combat applications for use in dangerous situations.

We must always expect our opponent to have advantages over us, such as size, speed, and power. By using the practical and effective method of Wing Chun we can overcome the adversary.
