Separate training would cover all the static type of attacks such as grabs, chokes, knife slashes etc. All have to be practiced at safe speeds. Training to hit with speed and power was a separate practice again.
By this time the ladies had trained random sticking hands practice, so they didn’t have to think about what to do, once in contact.
At this time, there was no YouTube and the ladies had not met with any Wing Chun Masters. That would come later.
These days, every fighting art has improved and many ladies now are pretty good fighters in any art. In the 1960’s there were of course pretty good women fighters in Karate and TaekwonDo. The ladies in the Filipino arts and arts like Silat were also good but not much information was available to us about these arts at the time.
These days the women MMA fighters are very good. These days we are blessed with having YouTube videos about every kind of fighting art. Martial arts are never static, they all constantly evolve.
Often what does not evolve is people’s biased opinions about what art is or isn’t good based on a few random samples of fighting they have seen. They use this limited experience to draw generalized conclusions about a whole art. It’s not the art but the person behind the art that counts anyway.
Someone who has a fighting brain can make any art work.
