Negative Positive
Title: Innovative and effective
Review: Griffith utilizes a distint core approach that focuses on all the planes (thus the "3D") giving a complete and total workout that is not only effective, but attainable. Much in the way of fitness is geared toward advanced fitness people, but this DVD is one anybody can use, without selling some gimmick or ineffective toy like so many others. If you want REAL abs then get this video.
