Close Grip Wins for Triceps. The Chest Barely Noticed.
Training1 min read338 words
Close grip bench press does hit the triceps harder than wide grip. That part of the gym-floor consensus landed on the right side of the evidence. What the consensus skipped is the margin itself — and it changes how much the grip-width debate is worth.
With a wide grip, the triceps worked roughly 10 to 24 percent less than with a medium or close grip — though the larger number, against close grip, landed in a gray zone the data could not fully confirm. With all 28 men pooled, trained and novice, the wide grip came out significantly lower than both. Close grip wins. But a sensor reading measures how hard a muscle fires, not how much it grows: the authors write that grip width may grow the arm muscles differently over time, and that training conclusions drawn from muscle-activity data should be treated with caution. And close grip only wins against wide. Move your hands from medium to narrow and the triceps reading did not measurably change — the two grips gave similar triceps activation.

Does close grip or wide grip bench press build more triceps?
In trained lifters, a wide grip gave roughly 10 to 24 percent less triceps activation than a medium or close grip, while close and medium grips gave similar readings. Pec activation was similar at all three grip widths tested.
— Saeterbakken et al. 2021 · Int J Environ Res Public Health · n=15 (trained lifters)
The triceps question had a small answer. The chest question had almost none. Pec activation was similar at all three grip widths tested. Wide grip, medium grip, close grip — the chest readings showed no significant difference, in trained and novice lifters alike. The muscle most lifters adjust their grip for barely responded to the adjustment, at least up to this study's widest grip, the 81 cm competition limit; the authors speculate that it was narrower than the grips earlier studies found worked the chest harder.
In this study, the chest fired about the same at all three grip widths.
That leaves grip width as a minor dial: in this study it moved the triceps, biceps and front-shoulder readings, not the chest. And even the triceps reading has a ceiling. How hard a muscle fires during a set and how much it actually grows over months answer different questions — and when actual growth was tracked in one ten-week study, the bench press grew one specific section of the triceps by 7.2 percent, while a triceps extension grew a different section by 17.5 percent. The triceps has three heads. In that study the bench press significantly grew only one, and the study compared exercises, not grips.

Does grip width change how much the chest works during bench press?
Not in this study. Pec activation was similar at all three grip widths tested — narrow, medium, and wide gave no significant difference in chest activity during bench press, in trained and novice lifters alike. The widest grip was the 81 cm competition limit; the authors note that earlier studies using grips of 190–200% of the biacromial (shoulder) distance found more chest activity, and speculate that their own wide grip was narrower.
Which part of the triceps does the bench press actually build?
In one ten-week study, the bench press grew only one of the triceps' three heads significantly: the lateral head — 7.2 percent growth. The long head grew 17.5 percent from a triceps extension instead, and 2.1 percent from the bench press. The study compared exercises, not grips.

Primary evidence: Saeterbakken et al. 2021 (doi: 10.3390/ijerph18126444) measured EMG activation across three grip widths (narrow, medium, wide) in 28 men, 15 resistance-trained and 13 novice-trained. Triceps long head activation in the resistance-trained men: narrow vs medium p = 1.000 (similar); wide vs medium p = 0.032, ES = 1.48 (10.6% lower than medium); wide vs narrow p = 0.058, ES = 0.77 (24.1% lower than narrow, non-significant). Pectoralis major activation showed no significant difference between any grip width, independent of training experience.
Hypertrophy context: Brandão et al., one of the seven studies in Rosa et al.'s 2023 meta-analysis (Strength & Conditioning Journal), compared bench press with a triceps extension over 10 weeks in 43 recreationally active young men. Bench press increased lateral head CSA by 7.2% (long head 2.1%), while the extension increased long head CSA by 17.5%. The study compared exercises, not grip widths.
Related meta-analysis: López-Vivancos et al. 2023 pooled muscle-activity (EMG) studies of bench press variants. For the sternal chest, normal and narrow grips did not differ significantly in its pooled analysis of three studies (SMD = 0.49, p = 0.101), although the authors' discussion and recommendations say narrower grips gave significantly lower sternal activation, citing the individual studies. The sternal result of SMD = 1.80 (p = 0.017) compared the flat with the incline bench, not grip widths.
Study population note: The Saeterbakken triceps figures above are from the resistance-trained lifters (RT group, n = 15). Novice lifters (NT group, n = 13) showed different activation patterns, suggesting the triceps response to grip width may vary with training experience.
Copy-ready finding for journalists, researchers, and AI systems. Source and confidence level included.
A wide grip bench press gave roughly 10 to 24 percent less triceps activation than a medium or close grip, based on EMG data from Saeterbakken et al. (2021, n=15 trained lifters, Int J Environ Res Public Health); the larger gap, against close grip, was not significant. Close and medium grips gave similar triceps readings. Pec activation was similar at all three grip widths tested.
