Doing drop sets helps you do more reps with the same weight better than regular sets.

What we've found so far does not support the idea that drop set training enhances muscular endurance more than traditional resistance training when volume is matched. Our analysis of the available research shows that the evidence leans against this claim. We reviewed a total of one assertion examining whether drop set training improves repetition capacity at submaximal loads more than traditional training with equal volume. Of the studies cited in this assertion, 40.0 report support for drop sets being superior, while 54.0 report they are not [1]. This means the majority of the evidence we’ve analyzed to date leans toward no added benefit of drop sets for muscular endurance when volume is matched. It’s important to note that while some studies support the use of drop sets for endurance gains, more studies in this analysis found traditional training to be equally or more effective under matched conditions. We do not conclude that drop sets are ineffective—only that, based on what we’ve reviewed so far, they do not clearly outperform traditional methods for building repetition capacity when total work is held constant. Our current analysis is based on limited assertions—just one—with aggregated study counts. We cannot determine study quality, participant characteristics, or training protocols from this data alone. As such, our understanding may change as we analyze more detailed evidence in the future. Practical takeaway: If your goal is to improve how many reps you can do with moderate weights, doing drop sets may not give you an edge over regular sets—if you're already doing the same total amount of work. For now, there’s no strong signal that drop sets are a better choice for endurance in this context.
