This exercise manual is designed to provide the user (beginner to advanced) a simple yet complete guide to cross-training. Each uniquely designed exercise Phase (1-5)and concurrent circuit routines (1-6) incorporate interval aerobic exercise with total body resistance (weightlifting) training based on the Do It Right Health & Fitness principles developed by Dr. Sardone author of The Naked Truth: Overweight, Overwhelmed and Confused.

These principles are centered on well-timed and gradual progression of exercise intensity, duration and sequencing designed to prevent adaptation and "burnout," and to continually challenge the cardiovascular, muscular and metabolic systems to improve.
