Straps help you hold onto the bar better, so your hands don’t give out before your legs and back are done working.
Scientific Claim
Use of lifting straps was associated with improved grip security during maximal isometric pulling, potentially reducing grip fatigue as a limiting factor in force production among healthy young males.
Original Statement
“primarily by improving the grip on the bar, compensating for low grip strength, and alleviating fatigue in the gripping muscles.”

Assessment Explanation
No direct measurements of grip fatigue, EMG, or grip strength were reported; the mechanism is speculative and not empirically tested in this study.
More Accurate Statement
“Use of lifting straps was associated with improved isometric mid-thigh pull performance in healthy young males, and the authors hypothesize this may be due to reduced grip fatigue or improved grip security, though these factors were not directly measured.”
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 reduce grip muscle fatigue during maximal isometric pulling, as measured by EMG or grip strength decline.
Whether lifting straps reduce grip muscle fatigue during maximal isometric pulling, as measured by EMG or grip strength decline.
What This Would Prove
Whether lifting straps reduce grip muscle fatigue during maximal isometric pulling, as measured by EMG or grip strength decline.
Ideal Study Design
A double-blind crossover RCT of 25 healthy males performing three 10-second isometric mid-thigh pulls with and without straps, measuring surface EMG of flexor digitorum superficialis and grip strength pre/post each set, with 7-day washout; primary outcomes: EMG amplitude decay and grip strength loss.
Limitation: Does not assess long-term training adaptations or transfer to dynamic lifts.
Prospective Cohort StudyLevel 2bWhether habitual lifting strap users show less decline in grip strength over multiple sets of heavy pulling exercises.
Whether habitual lifting strap users show less decline in grip strength over multiple sets of heavy pulling exercises.
What This Would Prove
Whether habitual lifting strap users show less decline in grip strength over multiple sets of heavy pulling exercises.
Ideal Study Design
A 6-week prospective cohort of 40 resistance-trained males performing 3x5 deadlifts weekly, randomized to use or not use straps; measuring grip strength (handgrip dynamometer) before and after each session.
Limitation: Cannot isolate strap effect from other training variables.
Cross-Sectional StudyLevel 3Whether athletes who use lifting straps regularly have higher baseline grip strength or less grip fatigue during maximal efforts.
Whether athletes who use lifting straps regularly have higher baseline grip strength or less grip fatigue during maximal efforts.
What This Would Prove
Whether athletes who use lifting straps regularly have higher baseline grip strength or less grip fatigue during maximal efforts.
Ideal Study Design
A cross-sectional comparison of 30 powerlifters who use straps habitually vs. 30 who do not, matched for training age, measuring grip strength endurance (time to 50% decline) during a 30-second maximal isometric grip test.
Limitation: Cannot determine if strap use causes better grip endurance or if those with better grip avoid straps.

The Effect of Lifting Straps Use on Isometric Mid-Thigh Pull Strength Performance
The study found that using lifting straps helped guys hold onto the bar better and their hands didn’t get as tired, so they could pull harder — exactly what the claim says.
