I train kung fu...are stand up is rly smooth and flowing, some of the styles that we do involve trapping arms, and cornering. Since my school is so mixed, are style is very different everyone seems to be using a front stance, since its good for punches and for med-high kicks. But we switch from so many stances not even to bother with which stance there in and determind what can hit u and what cant. staying lighting on the feet and working things we call set-ups. Where u hit and attempt to hit them in a certain area making them block using ur other hand or leg and go for the opening.
