There are three parts to every workout: the main work, supplemental, and assistance work.
The main work can be done with either the 5/3/1 scheme or the 5’s PRO scheme. There are others but these are the two main ones. You can find the percentages and details in the book.
Supplemental work is done with the same lift as the main one or a different one (explained in the book). Every template has different supplemental work and explains reps, sets, and weight. Boring but big is an example of a supplemental template. FSL 5x5 is another example.
Assistance work can be done with basically any paradigm. He usually recommends 25-100 reps (divided between however many sets you want) of a push, pull, and core or leg exercise. You will find a list of exercises from each category in basically every book.
This defines the structure of a workout. Plug in the exercises and weights for each week and you have the program.
