Using straps might help you pull harder on a machine, but we don’t know if that makes you stronger when you actually lift a barbell off the floor.
Scientific Claim
Use of lifting straps was associated with higher isometric mid-thigh pull force in healthy young males, but the study provides no evidence that this translates to improved one-repetition maximum (1RM) performance in dynamic lifts such as deadlifts.
Original Statement
“Strength and conditioning coaches may play a significant role in improving athletes' 1RM performance by incorporating the use of lifting straps, especially in pulling exercises involving high weights, according to athletes' training goals.”

Assessment Explanation
The study did not measure 1RM or dynamic lifting performance; therefore, any claim linking straps to 1RM improvement is unsupported by the data.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Randomized Controlled TrialLevel 1bWhether lifting straps increase 1RM deadlift performance in trained individuals.
Whether lifting straps increase 1RM deadlift performance in trained individuals.
What This Would Prove
Whether lifting straps increase 1RM deadlift performance in trained individuals.
Ideal Study Design
A double-blind, crossover RCT of 30 resistance-trained males performing 1RM deadlift tests with and without lifting straps (counterbalanced, 7-day washout), using standardized barbell setup, foot position, and coaching cues; primary outcome: 1RM force (kg).
Limitation: Does not assess long-term adaptation or safety with chronic use.
Prospective Cohort StudyLevel 2bWhether habitual lifting strap use over 12 weeks leads to greater 1RM deadlift gains compared to non-use.
Whether habitual lifting strap use over 12 weeks leads to greater 1RM deadlift gains compared to non-use.
What This Would Prove
Whether habitual lifting strap use over 12 weeks leads to greater 1RM deadlift gains compared to non-use.
Ideal Study Design
A 12-week prospective cohort of 50 trained males performing 3x5 deadlifts weekly, randomized to use or not use straps; measuring 1RM deadlift at baseline, 6, and 12 weeks, controlling for training volume and nutrition.
Limitation: Cannot control for self-selection bias or coaching differences.
Cross-Sectional StudyLevel 3Whether athletes who regularly use lifting straps have higher 1RM deadlifts than non-users.
Whether athletes who regularly use lifting straps have higher 1RM deadlifts than non-users.
What This Would Prove
Whether athletes who regularly use lifting straps have higher 1RM deadlifts than non-users.
Ideal Study Design
A cross-sectional comparison of 60 powerlifters matched for age, body weight, and training experience, comparing 1RM deadlift performance between those who use straps in training (>80% of sessions) vs. those who never use them.
Limitation: Cannot determine causality — stronger lifters may prefer straps.

The Effect of Lifting Straps Use on Isometric Mid-Thigh Pull Strength Performance
The study found that lifting straps help people pull harder when standing still and gripping a bar, but it never tested whether they help people lift heavier weights in real deadlifts — so we can't say for sure if straps make you stronger in actual lifts.
