What annikan skywalker said.

I know the two most obvious ones I have seen are swingers rotating on the back stroke as though they were swing and then do a hitter's motion into the ball.

The other I have seen is bent plane line resulting from usually taking the club too deep, it also matches the depth when they are at the top but yet they are only waste high.

Analyze your stroke with what he pointed out. It will probably pop out at you.
