Your Best Abs is revolutionary in its approach, but the research behind its benefits has been around for years. The premise is simple: Train the abs as they are designed to work, not by doing crunches and sit-ups, but by properly bracing the core. The purpose of the abs is to resist spinal extension-to brace and hold, not to push and pull.
