Grip choice matters
A new explainer breaks down how pronated, supinated and mixed grips change muscle recruitment — and argues simple grip changes can meaningfully affect strength gains and overuse risk on deadlifts and pull‑ups. The piece is a practical read for lifters wanting targeted adaptation without swapping exercises. (menshealth.com)
A 2016 EMG study of 19 trained men found pronated pull‑ups produced a peak middle‑trapezius activation of 60.1% MVIC versus 37.1% MVIC for a neutral grip, and concentric phases showed higher brachioradialis and biceps activity than eccentrics. (doi.org/10.1016/j.jelekin.2016.11.004) A University of Salford review reported that using rotating handles or a pronated hand orientation tends to produce the greatest latissimus dorsi activation during pull‑ups and lat‑pulldowns, while grip width had no clear effect on lat activity. (researchgate.net) A separate EMG analysis concluded that overall muscle activation across pull‑up grip orientations is broadly similar, meaning targeted adaptations come from modest shifts in which muscles peak during concentric or eccentric phases rather than wholesale recruitment changes. (doi.org/10.1016/j.jelekin.2016.11.004) A video‑based epidemiology study of distal biceps tendon ruptures reviewed 35 suitable injury videos and found 25 ruptures occurred during deadlifts, with every mixed‑grip deadlift rupture happening on the supinated arm. (journals.sagepub.com/doi/pdf/10.1177/2325967121991811) That same paper cites historical DBBTR incidence estimates of about 1.2 per 100,000 people per year and a more recent operative incidence of roughly 5.35 per 100,000 patients per year, highlighting that operatively treated ruptures are more commonly recorded in modern series. (journals.sagepub.com/doi/pdf/10.1177/2325967121991811) Coaching and sports‑science guidance points to hook grip and lifting straps as common ways to maintain load without an alternated supinated hand—hook grip preserves bilateral pronation to reduce biceps tendon stress and is standard in Olympic lifting, while controlled studies have examined straps’ effects on grip security and movement velocity during deadlifts.
