The Claim
Training to momentary muscular failure reduces the number of repetitions completed per set and decreases volume in specific movements, despite maintaining equivalent total session volume compared to non-failure training in trained men.
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 trained men, lifting until muscle failure results in fewer repetitions per set and lower volume for individual exercises, but the overall total workload for the entire workout remains the same as when stopping short of failure.
See the scientific wording
Training to momentary muscular failure reduces the number of repetitions completed per set and decreases volume in specific movements, despite maintaining equivalent total session volume compared to non-failure training in trained men.
When muscles are pushed to complete exhaustion, they produce excessive waste products and sustain microscopic tears, which disrupt their ability to generate force. This forces the body to stop performing repetitions earlier in each set, even though the total amount of work across all sets remains unchanged.
What the research says
1 studyWhen people lift weights until they can't do another rep, they end up doing fewer reps per set and less total weight in some exercises—but the overall workout weight stays about the same as when they stop before exhaustion.
