O.J. Simpson's highly anticipated exercise video, taped two and a half weeks before the killings, is played before the jury. O.J.'s doctor testified earlier that his patient's arthritis made him physically unable to commit the murders. The fitness trainer from Simpson's exercise video, as well as the photographer who shot the video, also testify. O.J. Simpson's defense team continues the conspiracy phase of their case, calling police detectives and Simpson's housekeeper to discuss packing habits, his Bronco, a broken glass from Chicago and the bloody socks.
