Since it's 5+, 3+, and 1+, it's usually a bit more than 3 x 5 and 3 x 3 and 5, 3, 1. That last "or more" set really forces you to push hard with a weight heavy enough to matter to you in an exercise that uses a lot of musculature. Especially early on, if you really do 90% of your 1RM and then follow the percentages, you can get a lot of reps in.nygmen wrote:A lot of people are going to need more volume that 3x5 at 65%,75%,85% and 3x3 at 70,80,90, or whatever the %'s are.
And if you need more volume, there are so many options - some people do another back-off AMRAP set, you can do the 5 x 10 "boring but big" (or is it "big but boring") and keep the rests short, you can swap in higher-volume accessory work. So many options once you bang out your 5/3/1 sets. You can really use it to answer the question, how do I program the sets, reps, and weights for my compound exercises? From there, do whatever else you need to do.
Still I'd think it was a better approach for what it was designed for - getting strong (and big) with built-in adjustments for how you feel that day.
