What rep ranges should I use?

For each of the exercises listed in your program, you will have a recommended repetition range (e.g. 6-10 reps, 8-12 reps, etc.). The weight that you select for that exercise should allow you to do the at least lower end of the rep range (e.g. 6 or 8) with proper form, but no more than the upper end of the rep range (e.g. 10 or 12).
