Drop sets let you get the same muscle-building results in about half the time because you don’t rest between weight drops.

Drop sets can make your workout much shorter — up to 70% less time — than regular sets, because you do more work without resting, but this wasn’t proven in the study, just noticed in two of the five studies.

Drop set training enhances muscular endurance (repetition capacity at submaximal loads) to a greater extent than traditional resistance training protocols with matched volume.

If you're already experienced with lifting weights, doing drop sets (lowering the weight after failure) doesn't help you get stronger than doing regular sets, as long as you do the same total amount of work.

Drop set training produces equivalent muscle hypertrophy in significantly less training time compared to traditional resistance training, resulting in greater hypertrophy per unit of time.

If you do the same total amount of work, using drop sets won’t make your muscles bigger or stronger than doing regular sets over two months.
