Sorry for the typos try this instead

The trail arm, the right arm for the right handed golfer, is always exerting a downward and onplane push. Picture good ole Grandpa using his right arm to pat the top of 6 year old Johnny's head. This extention of the right arm is held in check by the inert left arm--"checkrein" action. The left thumb may feel the pull of this right arm extensor action, specifically the heel section of the right hand will be pushing downward against the left thumb.
