The Claim

In resistance-trained males performing bench press exercises to momentary muscular failure with one-minute rest intervals, performing additional sets beyond four results in significantly reduced mechanical tension and metabolic stress, as indicated by measurable declines in movement velocity and time under tension, while still maintaining non-negligible output.

How it works
3 studies reviewed
In plain English

For trained men doing bench presses to failure with one-minute rests, doing more than four sets reduces the physical load and metabolic demand on the muscles, as shown by slower movement and less total time under tension, but does not eliminate the stimulus entirely.

See the scientific wording

In resistance-trained males performing bench press exercises to momentary muscular failure with one-minute rest intervals, additional sets beyond four contribute significantly reduced—but not negligible—mechanical tension and metabolic stress, as evidenced by measurable declines in velocity and time under tension without complete abolition of output.

Why this might work

When someone lifts heavy weights until they can't do another rep, their muscles get tired from too much acid and not enough energy, and their brain stops sending strong signals to keep pushing. Each extra set makes them slower and weaker because the muscles can't contract as hard, even though they still move the weight a little.

  1. Study: Influence of Resistance Training Proximity-to-Failure, Determined by Repetitions-in-Reserve, on Neuromuscular Fatigue in Resistance-Trained Males and Females

    When trained men do bench presses until they can't do another rep, each extra set makes them slower and more tired, but they still get a workout—even if it's weaker than the first few sets.

  2. Study: Neuromuscular Fatigue and Metabolic Stress during the 15 Minutes of Rest after Carrying Out a Bench Press Exercise Protocol

    When trained guys do bench presses until they can't do another rep, their muscles get really tired and stay tired for a long time—even after resting. So doing more than four sets won’t give them the same punch as the first few, but it still does something.

  3. Study: Influence of different recovery intervals on time under tension, total training volume, and fatigue index in horizontal bench press exercise in young male wrestling athletes.

    When trained guys do bench presses to exhaustion with only one minute of rest, their lifts get slower and harder after the fourth set, meaning the workout gets less intense—but they’re still working their muscles, just not as hard.
