An Abs and Core Weight Training Circuit Routine that burns calories, builds a strong core and rock-hard abs, and keeps your waistline thin.
Plus the science and reasoning behind proper, effective abs training workouts! The abs training routine included in this book can be used in place of a "traditional" cardio workout and boring aerobic training and running programs. The problem with long-form aerobic training is that it down-regulates metabolism (one of the chapters explores the research behind this in detail), so that the trainee is forced to do more and more with less and less payoff. These circuits are designed to do just the opposite.
