Oi-zuki

(lunge push). Here the straight punch is used on the side of the advancing leg when stepping forward, usually into the forward or the diagonal straddle stance. It is very useful when closing in on an opponent.

With this technique, the hips should remain more or less square. The fist should reach the target at the precise moment at which the advancing foot is planted on the ground. In order to keep a strong balance, be very careful not to lean forward - any feeling of pushing forward into the attack must come from the centre of gravity.
