Vertical Punch
(Sewo Jirugi):

Vertical Punch: I'm a huge
fan of the vertical punch.
This strike is great for
slipping in between
someone's guard. Also,
from my personal fighting
stance I can fire off a
vertical punch as a counter
to my opponent attacking
me with a hand technique. I
simply move off line as I fire
away with a vertical punch.
This set up my rear hand for
a finishing blow. So, rather
than using a simple jab with
the forefist, you can also
employ a vertical punch.
