if he's shoving with his palms finger tips up, trap both of his palms flat against your chest, step one foot back and bend towards your opponent causing him to hyperextend at his wrists. He will have to yield his position and go with your lock to avoid breaking his wrists. Be careful with this technique.
this kinda works and I say kinda cuz there lots of factors, however but it could never ever break the wrists. ,might possibly get him to drop to one knee
