sd,
It sounds like from you're last thread here about powerlifting, that you're a beginner with the compound lifts and that you're mainly concerned with getting stronger. Could I suggest reading this thread about Rippetoe's program?:

Whether you choose to use his particular program or not, it's got a ton of good information, however you may want to consider doing it as it seems that this type of program is designed for beginners/intermediates.
In his program you do a "sets across" method. This means that after you warm up you do 3 sets at the same weight (except for deadlift, for these you only do 1 set). I'm doing a 5 X5 ramping routine but I use similar %'s that sirwazzles does. I start with 50% and add 12.5% every set until I get to my top set of 5. In the article that I linked, he has this to say about pyramiding:
"Pyramiding is an old-school bodybuilding type weight progression scheme where you start with a lighter weight and do a bunch of reps, then gradually increase the weight while lowering the reps. Its effectiveness is entirely dependent upon your goals and your exact methodology.
1 method of pyramiding for a bodybuilder, used as an example:
Warmups, then...
225 x 12
245 x 10
260 x 8
265 x 4
270 x 1 or 2
Note that the 12, 10 and 8-rep sets essentially obliterate the trainee, and that 2 more sets are performed, but with notably submaximal intensity (%age of 1-RM)? Since "heavy/hard" 8-12 rep sets are good for mass building, a good pump will occur, and the trainee will make some size gains for a period of time, but without some volume/intensity manipulation (or proper chemical assistance), the trainee will quickly stall on a program such as this. It can be VERY effective for periods of time, especially for well-trained individuals, but frequently the training emphasis ends up being placed on the lighter weights and higher reps, which burns the trainee out, rendering their last few sets too light to be of real use."
So it sounds to me that he's not too keen on doing pyramiding especially for novices.
