The Claim
In young women undergoing resistance training twice weekly for 8 weeks, performing preacher biceps curls leads to greater improvements in preacher curl strength (3RM) compared to incline biceps curls, with a mean difference of 1.88 kg (95% CI: 1.14, 2.62 kg), which supports the principle of strength specificity to training movement patterns.
What the research says
Supports is higher
Support is ahead, but a single strong opposing 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.
If young women do preacher curls twice a week for 8 weeks, they get stronger at that specific move compared to doing incline curls — it really helps to train the way you want to get strong.

In young women performing resistance training twice weekly for 8 weeks, preacher biceps curls are associated with greater improvements in preacher curl strength (3RM) compared to incline biceps curls, with a mean difference of 1.88 kg (95% CI: 1.14, 2.62 kg), supporting the principle of strength specificity to training movement patterns.
What the research says
1 studyStudy: Distinct muscle growth and strength adaptations after preacher and incline biceps curls
The study found that women who did preacher curls got stronger at preacher curls compared to those who did incline curls, which matches the claim exactly.
