The Claim
When training volume and effort (repetitions in reserve of 0–1) are matched, cluster sets and traditional sets produce comparable total training volume over an 8-week period in resistance-trained individuals, indicating that cluster sets do not inherently permit greater cumulative load despite the inclusion of intra-set rest periods.
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 resistance-trained individuals, cluster sets and traditional sets result in the same total amount of weight lifted over eight weeks when the number of repetitions and effort level are kept identical, even though cluster sets include short rests between repetitions.

When you push your muscles to their maximum effort, they reach a point where they can't produce more force, no matter how much rest you take between reps. This limit comes from how quickly the muscle uses up its energy and builds up waste products, and it doesn't change whether you rest briefly between reps or not. As a result, the total amount of weight lifted over time stays the same.
What the research says
1 studyEven though cluster sets take short breaks between reps, they don’t let you lift more total weight over time than regular sets when you do the same number of reps and push just as hard. Both types of training built muscle equally, so the breaks don’t give you an extra advantage.
