Standardization

One other insight I gained from the book, "Starting Strength", is the use of standardization for measurement.  In the program, you work with the same group of exercises and standardize the amount of sets and reps.  For example, the program calls for using 3 sets of 5 repetitions on most exercises.  When this can be completed with a certain weight, then next time you increase the weight. 

This takes the unnecessary complexity out of basic programs.  If a person does 5 sets of 10 with a certain weight, and then 3 sets of 8 with a different weight another day, it's difficult to measure progress.  Add in different repetition speeds and it's an even bigger mess.  Initially, I think it's better to just standardize things and focus on lifting heavier weights in good form.

There may not be anything magical about 3 sets of 5.  3 sets of 8 or 5 sets of 5, or some other combination may be equally as effective.  But the point is to pick a set-and-repetition framework and stick to it.
