A lot of women players struggle to throw boules to longer distances, so when I saw this photo on the Facebook page of Celia Crittenden, I just had to re-post it.
Good form is the key to gettting distance on a thrown boule. And in this photo Celia, one of the top U.S. women players, shows how to do it. Aside from the fact that she is squat pointing, note the full backswing of the throwing arm, which supports a strong throw. Note also the full backswing of the non-throwing arm, which keeps her balanced as she throws.
