What do you mean "backwards"? Should CMA remove kicking/grappling in order to enter boxing match?
If it's a "boxing" match why would they not do so ?
Boxing, BJJ, SANDA, and MMA are often used as testing grounds for practitioners of various styles, including CMA, to test and prove their effectiveness. In some cases, modifications are required to fit within the rule sets of these sports.
In my experience with those who boxed, I agreed not to use kicks. The long-arm techniques practiced in Tibetan White Crane (TWC) coupled with the foot work, provided me with a significant advantage.
Funny story...
A guy who was a wrestler wanted to try his skill on me..
His approach
Before he got in range to grapple I did what is called a cup choy "掬捶" (jū chuí)"
stopping at the bridge of his nose..not breaking it, as I should have..
Normally its done with a back hand "wing flap" preceding it,
followed up by what ever hand is appropriate for the situation.
In this case I stopped it...a friendly testing encounter....with another GI
both with some down time, waiting for war...
He looked up, laughed, picked me up and threw me...
Learned something, that day....
Grapplers can cover ground quite fast in an unorthodox way..
Kill the arms first, if you don't want to hurt them..
Back in the day did a lot of "testing"
good times, even when getting banged up at times..
Whata gonna do,,live for ever
