as with many tcma styles the movements are fluid and quite naturally follows the tensing of muscles at the moment of impact of the strike. Same with Xingyi. There is also a solid "Rooting" that your body mechanics has to try and get used to. Like the feeling of stepping in mud, much like some bagua stepping. For its the Root in Xingyi that generates that powerful strike.
I have practiced two methods of Xingyi movement, The first would be the soft and supple style of moving through the 5 fists and 12 animals, not tensing at all and focusing more on qi flow, and also doing the movements slower so that i can get a feel for that qi flow to the extremities. plus moving a little slower helps your body mechanics and eventually one does the stepping and movements correctly.
the other method is the stop action explosive power that you generate at the moment of impact or strike in the 5 fists set and the 12 animals. and the concepts in jkd are similar, actually that concept of relaxing when you go to strike and then tensing up at the moment of strike isnt souley a JKD idea. but in effect you arent really tensing up and becoming rigid when you impact i mean there is a certain amount of that when you hit anything, but you will find that the power generated in a more relaxed attack can be more damaging to the internal system of a body than a tensed up karate type of strike that may only do surface damage and "stun".
Help me out fellow xingyi practitioners, am i wording all this correct in general terms?
Peace TWS
It makes me mad when people say I turned and ran like a scared rabbit. Maybe it was like an angry rabbit, who was going to fight in another fight, away from the first fight.
