Below is an article I have put together on the importance of Periodization in a Training Program.

Periodization is defined as one’s training being broken down into discreet time periods called, macrocycles, mesocycles, and microcycles.  Macrocycles are commonly referred to as any given period that a training program will last, usually a year.  Mesocycles are the periodical breakdown within the Macrocycles.  Lastly, Microcycles are often referred to as one cycle in intensity, meaning that when following the rule that a workout of high intensity should be followed by a workout of low intensity before another high intensity workout can occur.  Microcycles are usually thought of as one week long, but can be as small as a one day deviation in the training program. 

                Given the fact one cannot maintain a high intensity program throughout an entire year and optimum fitness is achieved progressively over a long period of time.  Periodization is important to all those who have a specific goal they are looking to achieve.  Examples of this would include clients that just simply are looking to obtain a higher level of physical fitness,  a baseball player looking to better his game by next season, or a bodybuilder looking to improve his muscle mass before his next competition.  For the client trying to become more physically fit a periodized plan ensures that he will not only continue to gain strength, power, and muscle size but will not get bored with the program causing him to not finish it.  As far as the baseball player and bodybuilder are concerned not only does a periodized plan have the aforementioned benefits, but it also allows these types of individuals to peak at just the right time. 

                So to answer the question whether periodization is for everyone or not the answer is yes.  These types of plans allow for individuals to train to a specific goal without getting bored, without overtraining, and they decrease their chances of injury.
