Swimming Pic of the Week - Barry Murphy Drill

Another great day of filming in Ann Arbor.  Check out Irish Olympian Barry Murphy.

We're not just filming tremendous stroke technique, we're also filming specific drills of these athletes.  One of Barry's favorite drills is illustrated with the pictures below.  The drill will be available on www.goswimtv.com, but can you tell what's going on in the pictures below?

You can follow Barry on Twitter as he gets ready to compete in London.
