The Claim

Do drop sets make the rectus femoris muscle bigger than regular sets?

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

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.

See the scientific wording

In recreationally active young men, eight weeks of drop-set leg extension training causes greater hypertrophy in the proximal (30%) and mid (50%) regions of the rectus femoris muscle compared to traditional training, with effect sizes of 1.20 and 0.89 respectively, while no difference is observed in the distal (70%) region or in the vastus lateralis at any site.

What the research says

1 study

  1. Study: Drop-Set Training Elicits Differential Increases in Non-Uniform Hypertrophy of the Quadriceps in Leg Extension Exercise

    The study found that doing leg extensions with drop sets made the top and middle parts of one thigh muscle grow more than regular training, but didn’t help the bottom part or other thigh muscles — just like the claim says.
