In basic English, periodization is simply the organization and planning of training. In sport, this planning is usually based upon achieving maximum physical abilities (strength, speed, power, etc..) for a given competition or period of competitions. In bodybuilding, the training might be organized around a specific bodybuilding contest.

Most bodybuilders actually plan or instinctively “periodize” their training in line with specific goals anyway (lose body fat, bring up a lagging body part, etc ). In general, if you have a specific goal for a period of time, then essentially you are using periodization. Let’s take a look at where this concept originated but first, here’s a list of the common terms for the different stages and components of modern periodization:

• Training unit – Refers to the actual “daily” workout
• Microcycle – Usually refers to a week of training
• Mesocycle – Usually refers to a period lasting 2-4 months
• Macrocycle – The largest unit of time lasting anywhere form 1 to 4 years(Olympic cycle)
