Coordination Stretch

Here is a fun coordination and stretch move:

Seated bring R heel forward and R palm facing forward.

Then bring L heel forward and L palm facing forward.

Then bring the R foot back, pointing toes, and turning R hand back toward body and then the L foot back, pointing toes, and turn L hand toward body.  Repeat from beginning.

It looks like the ball is between calves but it's just under the chair.
