The Claim
In recreationally trained women, there is no significant difference in regional muscle hypertrophy of the upper arm between exercises with ascending resistance profiles (e.g., preacher curls) and those with descending resistance profiles (e.g., inclined curls) when measured across multiple anatomical sites along the acromion-to-olecranon distance; the absence of a significant group-by-region interaction (p = 0.544) indicates similar overall regional growth patterns between the two exercise types, despite within-group hypertrophy occurring.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For women who work out regularly, both preacher curls and inclined curls build arm muscle just about the same way — no matter where you look along the upper arm.
See the scientific wording
In recreationally trained women, regional muscle hypertrophy in the upper arm does not significantly differ between exercises with ascending versus descending resistance profiles when analyzed across multiple anatomical sites (50%, 60%, 70% of acromion-to-olecranon distance), as no significant group-by-region interaction was found (p = 0.544), indicating that overall regional growth patterns are similar between inclined and preacher curls despite within-group changes.
What the research says
1 studyThe study found that preacher curls made one part of the arm muscle grow, but inclined curls didn’t, even though both exercises were supposed to work similarly. So the results don’t back up the claim that they work the same.
