Mark Eccard, bjj bb who wrote a column on exercises in grappling magazine, was always raving about them being better them regular weights because the bands mimic the way your tendons and ligaments in how they are basically like a rubber band in how they stretch and the bands provide position and negative tension throughout the movement of a given exercise. He was also saying they build better muscular endurance for grappling and so forth.
