An Assisted Face Side Block is a side block because the blocking arm is to the side of the body. It is called a face block because it is face-high. It is assisted because the off-hand is part of the movement. The blocking fist is held face-high to the side of the body -- blocking arm bent -- with the palm of the fist facing one's head. The off-hand is held at the same height as the blocking-arm's elbow, in front of the chest with the palm facing downward.
