Periodization means “to divide into periods,” when defined by most dictionaries. That’s also the way that I view this term as it applies to strength training. I’m a big believer that some form of change in a routine every three or four months or so is as good mentally as it is physically. In addition to this, as noted in some previous articles, I like to have a day or two each month when I mix things up a little bit. The change keeps enthusiasm high, helps you through sticking points, bolsters your motivation, and re- energizes your training.
I want to be very clear on one thing. When I use the word “periodization”—I actually call it “common sense periodization”—I’m not advocating the orthodox definition used by the NSCA and some other organizations. I find that definition illogical. I don’t believe in a “hypertrophy phase” as being separate from a “strength-building” phase. There are also other aspects of the orthodox definition that I don’t agree with, but rather than get into all of that I’d rather just focus on my definition.
