Let’s discuss the pros and cons of each option for, say, an 8x3 program:
Choose a weight that you will be able to get 3 reps with for all 8 sets, approaching failure on the last set.
Choose a weight that you will be able to get 3 reps for a few sets and do as many reps as you can for the remaining sets. If you can get 3 reps for all 8 sets, you need more weight.
Change the weight every few sets to match the rep scheme. (for example: set 1=3x265, set 2=3x275, sets 3&4=3x280, sets5-7=3x275, set 8=3x270) Chad Waterbury told me that this was the best option for his ABBH routine.
Gradually build up the weight so that early sets are relatively easy, with the heaviest set being last. I believe Westside uses this, except with singles.
Is one of these methods better than the others for strength, while another is best for size, or is it important to incorporate all of these methods?
