Simple question -- about sternum?

[jerry1967]

Does the sternum move laterally in the back swing and forward swing? If it does move is there a certain distance for each club?

Of course -- when we speak in 2-D terms. Every rotary action in 3-D can be viewed as linear in 2-D unless the observed point is in the axis of rotation.
