There are many complicated definitions for periodization, but the term simply means the division of the overall training program into periods which accomplish different goals.
Periodization is the modulating of volume, intensity, and frequency over time, to both stimulate gains and allow recovery.
In some programs for example; volume is decreased during a training cycle while intensity is increased. In this template, a lifter would begin a training cycle with a higher rep range than he will finish with.
For this example, the lifter has a 1 rep max of 225 lb:
|Week||Set 1||Set 2||Set 3||Set 4||Set 5||Volume Lbs.||Peak Intensity(Last Set)||% of 1 Rep Max(Last Set)|
|1||95 lb x 8reps||100 lb x 8reps||110 lb x 8reps||115 lb x 8reps||120 lb x 8reps||4,320||73%||52.5%|
|2||105 lb x 8reps||110 lb x 7reps||115 lb x 7reps||125 lb x 7reps||130 lb x 7reps||4,200||79%||57.75%|
|3||110 lb x 7reps||120 lb x 7reps||125 lb x 6reps||135 lb x 6reps||140 lb x 6reps||4,010||84%||63%|
|4||125 lb x 6reps||130 lb x 6reps||140 lb x 6reps||145 lb x 5reps||155 lb x 5reps||3,870||88%||68.25%|
|5||130 lb x 5reps||140 lb x 5reps||150 lb x 5reps||155 lb x 5reps||165 lb x 4reps||3,535||94%||73.5%|
|6||140 lb x 4reps||150 lb x 4reps||160 lb x 4reps||165 lb x 4reps||175 lb x 4reps||3,160||99%||79%|
This is an example of periodization where the number of repetitions decreases while the weight increases.
