This is from my 2002 personal video training diary. This was meant for my personal reference for a video series I was planning and not as an instructional video.
The Lop Sao Switch is one of the precursor energy drills to Chi Sao (Sticky Hands). I learned this on my very first JKD class under Bill Mattucci during 1991. Applying it to the dummy takes a bit of adjusting and getting used to so this is an intermediate technique that you will develop into.
This demo shows you how to practice this exercise on the Wooden Dummy when a partner is unavailable.
As a beginner you may extend your arms further due to lack of wrist flexibility but as you progress move in closer testing your wrist flexibility using PROPER FORM as I do in the video.
The closer you get to the dummy the more difficult it will be to have correct form but keep at this and your wrist flexibility will improve as will your strength.
Your shoulders, hips, and feet should ALWAYS be in line. Otherwise you are off balance and will not generate power.
The picture on the left is how you DON'T want to look.
His hips are beyond his heels and the torso is leaning forward beyond his toes. Don't be like this. It's not Wing Chun. It's not JKD. Kinda looks like Silat. It's not art, no street practicality, and worthless in sport. 3/3 fail.
The key is to focus on Centerline using springing energy while honing your technique. This has and ALWAYS will be my primary focus on using the Mook Jong. I can not stress this enough. This is NOT an impact training tool.
I trimmed this video to prevent the constant repitition and the squeek of my arms against the wooden arms. Constant repetition on the Dummy will hone your Wing Chun skills like no other piece of training equipment.
This is the last post from the 2002 video. This was fun to revisit and sparked some creativity in wanting to do more.
