Wing Chun: Sil Lim Tao 

You Are Very Welcome thank you for the feed back

The Energy in Wing Chun Comes through the spine. You combine your breathing with your strikes. Make sure you use short exhales when you strike. The Triceps extend the arms so training the wall push ups help greatly. Relax the biceps when you punch.Use full extension on your punches. The power is added also by stepping while you hit. Using your opponents force as he tries to sire you stepping off the line and stepping toad him at an angle to avoid his force redirecting it with your books and striking. It become similar to aa head o collision except your punch to his body hope this helps all the best and thank you for your question
