Expansion vs. rotation

[toby]

Some say expand, while others say rotate to release.

What are your thoughts. Isn't rotation complete at full draw.

How would you describe expansion?

[Jake Scott]

I think both expansion and rotation are ways to go about achieving proper alignment.  I personally am more of a rotator.  I achieve anchor, then my string hand elbow comes around in the "j-shape" that is often discussed here.  I would say like many other thinks it's a matter of personal preference.

I will be interested to hear what Arne, McDave, and Terry have to say.  Good question.

It really depends on the "system" you are using.

In the NTS, the rotation continues on the string side (shoulder) and in turn "presses" the bow shoulder and consequently the bow arm out towards the target.  This movement of the bow arm is passive on the bow side and caused by the string side shoulder. This bow side movement is caused by what the NTS calls the ratio of circular movement.  Where a SMALL (internal/invisible) rotational movement of the string shoulder causes a slightly larger linear (ABOUT 1/8 inch) movement of the bow side which is enough to actuate the clicker (if used).

In other systems, expansion is variously described as: opening the chest, pressing the bow hand out to the target or even inhaling a little to expand the chest.

What ever "system" or "theory" one subscribes too, expansion is a very small movement that leads to release and follow through.

I'll add that for MOST traditional shooters, this movement will have varying degrees of attention or understanding and for many, it can be just too much theory and not enough recognized result to worry about.

I really liked that explanation Arne.   It's not often we hear just how the actions of what brings the shot to conclusion (rotation or expansion) should effect the bow arm side.

Arnie,  great explanation. I have rebuilt my shot sequence and slowed things down quite a bit. Trying to pause on target then expand into release. When I try to rotate it feels forced.
