Different ways of lifting weights—like regular sets, pre-exhaustion, or drop sets—all work just as well for building muscle strength, endurance, and size if you do the same total amount of work. Changing the method doesn't give you better results.

If you do the same total amount of exercise, three different workout styles—regular weight training, pre-exhaustion, and drop sets—all work just as well for building muscle strength, endurance, and size.

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

Doing drop sets (lifting heavy, then lighter weights without rest) builds strength just as well as doing regular sets with the same total weight, at least in young men who already lift weights.

Drop set training, involving multiple load reductions without rest until momentary failure, produces skeletal muscle hypertrophy equivalent to traditional resistance training with multiple sets.

If you do your workouts with either drop sets, rest-pause, or regular sets — but do the same total amount of work — your muscles grow about the same size in your thighs.
