More Muscle in One Spot with Less Time?
Drop-Set Training Elicits Differential Increases in Non-Uniform Hypertrophy of the Quadriceps in Leg Extension Exercise

Two ways to train legs: one is normal, the other is doing extra reps right after getting super tired. The extra-reps way made one part of the front thigh muscle bigger — but only in the top and middle, not the bottom.
Surprising Findings
Drop sets caused 30% greater hypertrophy at the top of the rectus femoris (ES=1.20)—a massive effect—but zero growth difference in the vastus lateralis.
Most assume drop sets evenly stimulate all muscle fibers. This shows regional specificity—some muscles (or parts) are more responsive to fatigue-based techniques than others.
Practical Takeaways
Use drop sets on leg extensions if you want to emphasize the upper/middle front thigh—ideal for bodybuilders or rehabbing quad imbalances.

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.
The side muscle of your thigh doesn’t grow any more with drop sets than with regular sets—no matter where you measure it.
Doing leg extensions with drop sets (going to failure, then lowering the weight and going again) makes the front part of your thigh muscle grow more than doing regular sets, but only in the upper and middle parts—not the bottom or the side muscles.
Doing leg extensions with drop sets (going to failure, then lowering the weight and going again) makes the front part of your thigh muscle bigger in the upper and middle areas, but not the bottom part or the side muscle.
Muscles don’t grow evenly — some parts get bigger than others, and different muscles in the thigh respond differently to the same exercise.
