I’ve been a top set/back off set guy for a couple years now. I had been a JP guy since 2018ish and even remember when he used to post on here. I have made some adjustments though. I stick to this setup for chest and back days as both respond very well to it and I can reach true failure without killing myself. But legs, I’ve had to go more of a volume approach as I train alone. I can truly squeeze out a top set on chest with a Hammer Incline, fail on a rep and let that shit drop. But try doing that on a hack or leg press, impossible training alone. So if I cannot go 100%, I have to go 80% for more volume to try to get that same response…just pulling levers on intensity and volume.
And like QB said, I don’t train shoulders and arms this way either. I have 1 progressive overload movement on shoulder day, the rest is high volume. Arms is always volume and both respond better that way.
