Even though cluster sets let you rest briefly between reps, they don’t actually let you lift more total weight over time than regular sets—if you’re pushing just as hard in both.

Cluster sets and traditional sets elicit similar muscular hypertrophy: a volume and effort-matched study in resistance-trained individuals

Randomized Controlled Trial

2025 Jun

When people lifted weights with the same total effort and number of reps, whether they took short breaks in the middle (cluster sets) or not (regular sets), they got equally strong and muscular — so cluster sets don’t let you do more work.

Similar Assertions

By adjusting the weight based on how close you are to failure (RIR), both types of sets end up using about the same weight—even though cluster sets seem like they should let you lift heavier.

83%

Whether you take short breaks between reps or not, your body adapts by lifting heavier weights at about the same rate—as long as you’re pushing yourself to near failure each set.

81%

People who did more sets didn’t lift heavier weights—they just did more reps and sets. The weight stayed the same, but the total work went up.
