I have (and continue to) follow periodization strength programs based on the work of such authors as Tudor Bompa, PhD. He (along with several others based in the old Eastern Bloc nations) coined the word "periodization" to describe the process of organizing your training year into periods, or "microcycles", that emphacize the four main aspects of muscular physiological adaptation (general anatomical adaptation, max strength, power, and muscular endurance). Following his principal of planning for peak performance, I have managed to win several national and three world championships in rowing over the years. I am convinced I would not have had the success I have had (while helping raise four kids and having a full time job) without proper planning. I have learned to train smarter, not harder... While these programs were designed to meet the needs of athletes to attain peak performance at specific times of the year, the principles can be applied successfully to the general fitness enthusiast, particularly if one follows the specific guidelines about the need to develop a firm foundation of fitness as detailed in Dr. Bompas' books Serious Strength Training. I read Dr's. Fleck and Kraemers book "Optimizing Strength Training: Designing Nonlinear Periodization Workouts" thinking I would expand on my knowledge base. To my sincere dissapointment, I found their book to be poorly organized and written. Every chapter is filled with pleas to see the differences in their plan (which basically follows the basics of periodization, without all the organization). The authors' main point, it would seem, is that coaches and trainers should pay attention to their athletes or clients level of readiness to participate in a planned workout, and to be ready to adjust or abandon the workout if they aren't ready to give close to 100% effort. They also over simplify the Theory of Periodization, and present their plan as a nonlinear alternative. They fail to give proper credit to those who created the Theory of Periodization, not even mentioning Bompa's name anywhere in the text, or the Bibliography (Bompa, on the other hand, does cite the authors in his). Someone interested in learning to design an intelligent training program would be better off reading any one of Dr. Bompa's books.
