The Claim

Doing a tough set of arm curls followed by lighter sets without resting can make your biceps grow just as much as doing only heavy or only light curls over 8 weeks.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Doing a tough set of arm curls followed by lighter sets without resting can make your biceps grow just as much as doing only heavy or only light curls over 8 weeks.

See the scientific wording

A resistance training protocol using a single high-load set followed by drop sets to low-load without recovery intervals may increase elbow flexor muscle cross-sectional area in untrained young men after 8 weeks of training, similar to traditional high-load or low-load protocols.

What the research says

1 study

  1. Study: Effects of drop sets with resistance training on increases in muscle CSA, strength, and endurance: a pilot study

    This study found that doing one heavy set of arm curls followed by lighter sets without resting worked just as well as doing multiple heavy or light sets to grow arm muscles — and it took less time.
