The Wing Chun system emphasises the importance in practicing your forms on a daily basis. There are a total of 6 forms to learn:
Sil Nim Tao, Chum Kiu, Bil Jie, Mook Yun Jong, Luk Dim Boon Gwon and Baat Jam Do.
Every Sifu should be teaching you the forms to your level and then explaining the applications to each movement in the form.
If this is not evident, then practicing forms will surely be a waste of time for you. Forms should be practiced slowly and sometimes with plyometric movements. You must understand the purpose of what you are doing other wise it will just become an aerobic routine.
My SiFu once said to me ‘Wing Chun is an unforgiving art”. Sifu further explained that the Wing Chun system requires the practitioner to perform the movements properly. If your strikes or blocks are slightly out of structure, then your technique cannot manifest its full effectiveness.
Once you understand the combative approach to each movement in your forms, then you will be able to engage your mind and visualise combative scenarios in which the movement will be effective.
This is the path to true mastery in your Wing Chun. Attention to small detail is vital.
According to the source above, training your muscles in a particular movement can cause your muscle cells to adapt and develop muscle memory.
Likewise repetitive training on your forms will help you apply your Wing Chun more effectively.
The goal is to achieve natural movement with unnatural moves and develop unnatural instincts with natural instincts.
