Can 3-D movie technology improve an athlete's performance? Olympic gold medalist Dana Vollmer demos the future of athletic training

At the 2012 London Olympics, Dana Vollmer won the gold medal in the 100-meter butterfly and broke the world record. But her journey isn't over: She wants to swim faster.

The same movie magic technology that created creatures in James Cameron's "Avatar" is now helping Vollmer improve her swimming performance.

This morning on "Early Start," Vollmer talks with John Berman to demonstrate the amazing technology, along with Olympic movement advisor Milton Nelms and Chris Bregler, CEO of Manhattan Mocap that created the equipment.
