A C Shape Punch (also called a U Shape Punch) is a two-handed punch where one hand is above the other, so that the arms form a C shape when viewed from the side of the person punching. The upper arm is punching conventionally with the palm down, at face-height. The other arm is performing a turn-over punch meaning the fist is palm-up; for this arm, the fist is punching at abdomen-height. In a Wide U Shape Punch, the upper arm is held higher, as if punching to a height above head-height. Note: A Simultaneous Punch is also sometimes called a U Shape Punch.
