We are now putting you to work with a 12-week schedule divided into two six-week parts. Each part is intended to fully train the body. Each six-week cycle is again divided in two to vary the intensity and effectiveness of the schedule. This is an example of an advanced training technique called "periodization", a very effective method of forcing the body to grow. You change things so that your body cannot adapt to the loads it is subjected to. By keeping the body in limbo you force it to grow so that it can take on new forms of stress. Once you have passed the twelve weeks, you are ready for a more far-reaching program.
