Pair up offensive linemen on a line of scrimmage. The blocker aligns in a three-point stance with the defender in a challenge position. On the coach's command, the blocker sets up in the proper pass protecting position. From the set position, the blocker will punch the defender using proper technique (The punch should be made with the butt of the hands to the inside framework of the defender's body.). The drill should be conducted so that all linemen receive a sufficient number of reps.
