Is it really low volume? Or is my one rep (my circle), just different than others. My “on paper” rep could truly be four times the volume of someone else’s rep.
IMO volume is the most taxing on recovery, (and orthopedically) I want as few reps as possible total, to accumulate as many effective reps as possible. This is why EVENTUALLY I want most people training to failure.
Leave “bullets in the gun”, so down the road, increased volume is still an option.
The intensity advantage – if the stimulus of high force production is the limiting factor, it’s easier to add more high intensity (load) reps with lower volume, increased frequency. (Compare 10 working sets in one workout to the same volume in two workouts)
