When I taught my class, I asked my students to spar on the 1st day. They might not know what to do, but they could learn to move their head away from a incoming punch, and raised their leg to block a incoming kick. That would be good enough if they could do that on their 1st day.
Even if the round house kick exist in the Longfist system. It is not part of the solo drills training. One day in the sparring, I used a non-perfect foot sweep. It didn’t sweep my opponent down but it hurt my opponent’s leg big time. That day was the day that I found out how to use my round house kick.
I also found out that if I had right leg forward and my opponent had left leg forward (mirror stance), a hook punch could give me a perfect set up for my “hip throw” and I didn’t even have to spin my body. Before that day, I didn’t even know without body spinning, my hip throw could be possible.
We can learn a lot from the sparring that we can’t learn from our solo form training. I just don’t understand why some CMA teachers don’t use sparring as a valid teaching tool. The teacher can always gradually introduce his style principles one at a time into the sparring training. If you train this way, in two years, you will have some good Taiji fighters, XingYi fighters, Bagua fighters, Longfist fighters, … What’s your opinion on this?
