Using lifting straps might help you lift heavier weights and feel like you have a better grip, but we don’t fully know why yet.
Scientific Claim
Lifting straps may be associated with enhanced maximal strength and improved grip perception during resistance training, particularly in exercises like deadlifts and pulling movements, though the physiological basis for this remains unclear.
Original Statement
“Evidence suggests that LS can enhance maximal strength and grip perception.”

Assessment Explanation
The abstract uses 'evidence suggests' but the study is a narrative review with no primary data or experimental design, so causation or even strong correlation cannot be established. The verb should reflect association only.
More Accurate Statement
“Lifting straps are associated with reports of enhanced maximal strength and improved grip perception during resistance training, though this is based on experiential observations rather than controlled evidence.”
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 causally improve maximal strength and grip perception in trained individuals during standardized resistance exercises.
Whether lifting straps causally improve maximal strength and grip perception in trained individuals during standardized resistance exercises.
What This Would Prove
Whether lifting straps causally improve maximal strength and grip perception in trained individuals during standardized resistance exercises.
Ideal Study Design
A double-blind, crossover RCT with 40–60 resistance-trained adults performing matched deadlift and pull-up sessions with and without lifting straps, measuring 1RM load, grip force via dynamometer, and electromyographic activity of forearm muscles, with 1-week washout between conditions.
Limitation: Cannot determine long-term chronic adaptations or real-world training effects beyond acute performance.
Prospective Cohort StudyLevel 2bWhether habitual lifting strap use over months correlates with greater strength gains compared to non-users in a real-world training population.
Whether habitual lifting strap use over months correlates with greater strength gains compared to non-users in a real-world training population.
What This Would Prove
Whether habitual lifting strap use over months correlates with greater strength gains compared to non-users in a real-world training population.
Ideal Study Design
A 6-month prospective cohort tracking 200+ resistance-trained individuals who either consistently use or avoid lifting straps during pulling exercises, measuring monthly changes in 1RM deadlift and grip endurance, controlling for training volume and experience.
Limitation: Cannot rule out confounding factors such as training intensity or motivation differences between users and non-users.
Cross-Sectional SurveyLevel 3The prevalence of perceived grip improvement and strength enhancement among current lifting strap users in the general resistance training population.
The prevalence of perceived grip improvement and strength enhancement among current lifting strap users in the general resistance training population.
What This Would Prove
The prevalence of perceived grip improvement and strength enhancement among current lifting strap users in the general resistance training population.
Ideal Study Design
A survey of 1,000+ resistance-trained individuals asking about strap usage frequency, perceived changes in strength and grip, and training history, with objective strength data self-reported and validated via gym logs.
Limitation: Relies on self-report and cannot establish temporal sequence or causality.
Evidence from Studies
Supporting (1)
The study found that using lifting straps can help people lift heavier weights and feel like they have a better grip, especially during exercises like deadlifts — which is exactly what the claim says. It doesn’t fully explain why this happens, but that’s also admitted in the claim.
