For beginners lifting weights, pushing until you can't do any more reps doesn't give extra strength gains compared to stopping earlier, as long as you do the same total amount of work. Both ways lead to similar improvements in how much you can lift.
See the scientific wording
Training to muscle failure does not provide additional strength benefits compared to training without failure in either high-load or low-load resistance exercise when total training volume is equated in untrained men over 8 weeks, with both failure and non-failure protocols producing similar 1RM improvements within each load category.

Randomized Controlled TrialHuman2022
The study mostly agrees with the claim for high weights but shows small differences in strength gains for low weights with failure vs. no failure, so it doesn't fully support the claim that they're always the same.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

Muscle Failure Promotes Greater Muscle Hypertrophy in Low-Load but Not in High-Load Resistance Training
The study mostly agrees with the claim for high weights but shows small differences in strength gains for low weights with failure vs. no failure, so it doesn't fully support the claim that they're always the same.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Randomized Controlled Trial Comparing Muscle Failure vs. Non-Failure Training on 1RM Strength in Untrained Men with Equated Volume
RCT with untrained men randomized to failure or non-failure groups, equated total training volume, high- and low-load categories, 8-week duration, 1RM strength as primary outcome.
Prospective Cohort Study on Long-Term Strength Outcomes of Failure-Based Resistance Training in Novice Lifters
Prospective cohort following untrained men adhering to failure or non-failure protocols with equated volume, tracking 1RM changes over 8+ weeks.
Cross-Sectional Analysis of 1RM Strength in Trained vs. Untrained Individuals Using Failure and Non-Failure Methods
Survey and measurement study assessing historical training methods (failure/non-failure) and current 1RM in untrained and trained men with volume equating considerations.
Systematic Review and Meta-Analysis of Resistance Training to Failure on Strength Gains in Equated Volume Conditions
Systematic review and meta-analysis of RCTs and cohort studies focusing on untrained men, equated volume, high/low loads, 1RM outcomes, and 8-week duration.
