Nyrotic I love your fevor. Wow. This is your second post I really connected to. I suggest you try to practice or meditate on your Wing Chun everyday. Atleast get some phyiscal practice in six days a week. May be rest on Saturday so your body can rejuvenante. Some time around friday night to saturday. I read this is optimal time for your body to rest. If you believe Kevin Tredu book on Natural Cures they don't want you know about?
As for practice. I suggest you break up each day?
1.Sunday if you are off work try to Work out atleast 3 hours or more.
2.Monday strecth each leg and arm. (Five minute intervals) Per strecth.Work on Punches, Sil Lum Tao Steps
3.Tues: Strecth, Punches,Kicks Sil Lum Tao and Chum Kiu (Wooden Man)
4.Weds:Stectch Punches and Kicks and Sil lim Tao (Wall Bag)
5.Thurs:Strecth Punches and Kicks all forms and steps
6.Friday before sundown: Punches, Kicks Sil Lim Tao and Steps
7.Satuday Night work on Punches, Kicks, 3 Forms, Wooden man, Wall bag, Drills, Steps.
I try to work on forms and steps during work. So when I get home alls left to do is rest of drills punches and kicks. But as for over doing it. The more punches and kicks you throw the more your power will increase. The more you do Sil Lim Tao the more your Internal power will increase. On days you can not practice on your own. Try to do Sil Lim Tao and work steps. Thats not really hard at all. When you do forms envision a opponent infront of you an how your moves can interact with attacker. When you rest also try to read and watch videos about wing chun. This will help your understanding.
As for partners. Try to find people of other Arts or boxing to spar with. This will increase your Wing Chun greatly. An Dan Chi Sau why not teach it to Girlfriend or Brother or cousin so you have someone to do it with. This way you can work on Muscle memory. Sometimes I do dan chi sau on my own just as a drill. The more you practice the more your mind will open up and your understanding increase.
To achieve proficiency in a realistic amount of time? As of right now my training is limited to solo training, that means formwork, wallbag work, etc.
The thing is, I don't know how often I should train certain aspects on a daily basis? Any advice?
Also, I can't train chi sau regularly because all the others students of my sifu live so far away (He teaches in private one-on-one lessons).
