Periodization Methods by Karsten Jensen

What does a basic strength program look like with different Periodization systems?”

There is currently scientific literature on 4 different periodization systems:

  • Linear periodization
  • Reverse Linear periodization
  • Daily Undulating Periodization
  • Block Periodization.

It is important to understand that these systems are all examples of application of Periodization. Fundamentally, periodization is a strategy or principle for organizing long term training and specifically defined as a division of a longer training cycle in to different periods with different target training adaptations, structures and content of the training program

It is interesting to note that each periodization system appears in quite different variations throughout the scientific literature. This post gives a brief example of a basic strength program as it would look with a linear, daily undulating and block model.

Each example is based on training three days per week with barbell squat, barbell bench press and seated row for a total of 15 sets each day. For the case of brevity the example is disregarding repetition tempo, exercise order, rest periods and principles of progressive overload.

Linear Periodization

Linear periodization is a pattern of gradually increasing intensity and gradually decreasing volume. Each of the shown phases can last for 3-6 weeks.

  Muscular Endurance Hypertrophy Maximal Strength
Squat, 5 x 15 5 x 10 5 x 5
Bench Press 5 x 15 5 x 10 5 x 5
Seated Row 5 x 15 5 x 10 5 x 5


Daily Undulating Periodization

Daily undulating periodization does not have phases (meso cycles) like linear periodization. Rather, the variation in the training program exists WITHIN each week.

  Monday – Muscular Endurance Wednesday – Hypertrophy Friday – Maximal Strength
Squat, 5 x 15 5 x 10 5 x 5
Bench Press 5 x 15 5 x 10 5 x 5
Seated Row 5 x 15 5 x 10 5 x 5


Block Periodization

Block periodization – like linear periodization – involves a lot of variation between each meso cycle. In contrast to linear periodization each phase in block periodization is characterized by having 60-70% of the training time dedicated to a select portion of the training goals.

  Muscular Endurance Bench Press emphasis Hypertrophy

Squat emphasis

Maximal Strength Seated Row Emphasis
Squat, 3 x 15 9 x 10 3 x 5
Bench Press 9 x 15 3 x 10 3 x 5
Seated Row 3 x 15 3 x 10 9 x 5


Each system was created for different scenarios. Additionally, due to the Principle of Accomodation, none of these systems can said to be the “best”. In fact, it can be very beneficial to switch between systems after each macro cycle.
