I generally use the big lifts (Squat, Deadlift, BB Bench or DB, and Shoulder Press) to measure my progression. These are the heavy compound lifts. Remember the term "heavy" is relative meaning what is heavy to me may not be to you. Regardless, these lifts should be heavy to you. Not heavy as in 1 Rep power lifting, but light enough so you can do at least 5, but heavy enough where doing 8 is challenging. Since heavy lifting is taxing on the central nervous system, I usually leave 1 rep in the tank. If I go to failure of these lifts, I fry my CNS and the rest of my workout is shit.
I use several approaches when working with these lifts, but basically my working sets are in a lower rep range (5-8). I really try to focus on adding more weight to these lifts and as I said, find it easier to do so in a lower rep range. I don't do 1 Rep maxes or even 2- 3 Rep..that's more power lifting. Let's say your goal is to add 50lbs to your deadlift in 6 months, it will be much easier to make progression/strength gains in the 5-8 Rep range. 50lbs on the deadlift in 6 months is very attainable, that's only 9 pounds a month or 2.5pounds per week. In fact, I am willing to bet if you are feeding your body the energy it needs, you could exceed 50 pounds in 6 months. Same with squat. Both the squat and deadlift are involving large muscle groups so the gains will come faster on these lifts. Same concept applies to the Shoulder Press and Bench-DB or BB.
I either do straight sets - Deadlift Example : 345x7, 345x6, 345x5
OR
Pyramid Sets - DB Shoulder Press Example : 60x8, 65x8, 70x(5-8)
I structure my workouts around the big lifts. All the other exercises are normally in the 8-12 or 10-12 rep range.
